Wooden furniture knobs Button HL-036 for wardrobe: how to distribute 37, 53, and 74 mm across 24 facades

The working drawing of the wardrobe already has 24 mounting points. Eight belong to narrow facades of 300 mm, eight to medium ones of 450 mm, and another eight to doors of 600 mm. The handle shape is chosen: Button HL-036. The argument starts not about design, but about scale.

Putting the same 37 mm button on all 24 facades is the simplest order. But on a 600 mm door, such a handle will be twice as small relative to the facade than on a 300 mm drawer.

Putting 74 mm everywhere is also simple. Then the large door gets a confident accent, and on a 300 mm facade, the handle takes up almost a quarter of its width with its visible zone and starts to dominate.

The Button HL-036 has a rare advantage: one model is produced in three real sizes — 37×22×15, 53×27×18, and 74×29×25 mm. This allows keeping one design while changing the physical scale for different facades.

For our project grid, this results in an almost mathematically even system:

37 / 300 × 100 = 12,3%

53 / 450 × 100 = 11,8%

74 / 600 × 100 = 12,3%

That is, the small Button on a 300 mm facade, the medium on 450 mm, and the large on 600 mm occupy almost the same share of width.

That is why the preliminary specification looks like this:

• Button HL-036 37 mm — 8 pcs.;

• Button HL-036 53 mm — 8 pcs.;

• Button HL-036 74 mm — 8 pcs.

Total — 24 handles.

But this is not a universal formula for any wardrobe. First, you need to check the actual facade dimensions, handle positions, grip, door thickness, mirrored panels, opening of adjacent sections, and future finishing.

After such a check, you can buy furniture knob Button HL-036 not as "24 identical buttons", but as an exact batch of three size groups.

Wooden knob Button HL-036: one model in three physical sizes

The current card for Button HL-036 confirms three variants.

All three versions have "Prestige" polishing quality. The handle is supplied unpainted. The mounting kit is included in the price.

At the time of checking, each size is sufficient for a project batch of eight pieces. But stock levels change, so they need to be re-checked before payment.

37/53/74 mm should not be treated as conditional S/M/L without differences in geometry.

Not only size A changes:

• depth C increases from 22 to 29 mm;

• size D — from 15 to 25 mm;

• the grip area changes;

• the distance of fingers from the facade changes;

• the handle becomes visually more active;

• its shadow on the facade becomes more noticeable.

Therefore, it is more correct to consider the three Buttons as related but independent physical products.

Why 24 identical handles are not always the neatest order

Sameness is easily confused with unity.

If all facades have the same width, one handle size truly creates a clean repetition.

But in our wardrobe, the width changes by a factor of two:

300 → 450 → 600 mm.

Let's install the Button 37 mm everywhere.

Width share:

• on 300 mm — 12.3%;

• on 450 mm — 8.2%;

• At 600 mm — 6.2%.

On a large door, the same handle visually "shrinks" almost by half relative to the first facade.

Now let's set 74 mm everywhere:

• 74/300 = 24,7%;

• 74/450 = 16,4%;

• 74/600 = 12,3%.

On a 300-millimeter facade, the handle already takes up almost a quarter of the width by dimension A.

The problem is not that this is "wrong." Such contrast can be done intentionally.

The problem arises when the client wanted one calm rhythm, but got three different visual scales just because it's more convenient to put one size in the cart.

Button HL-036 37 mm on a 300 mm facade: about 12.3% of the width

Calculation:

37 / 300 × 100 = 12,3%.

If the handle is positioned strictly in the center of the facade, the nominal free field horizontally is:

(300 − 37) / 2 = 131.5 mm.

This is not a mounting offset, but visual arithmetic: it shows scale.

On a 300 mm facade, a 37 mm Button looks like a compact dot, but does not disappear.

For a drawer or narrow door, this can be a good balance between decorativeness and a calm field.

At the same time, size C is 22 mm, D is 15 mm. This means the actual grip needs to be checked not by the frontal diameter of 37 mm, but physically.

When 37 mm is especially logical to check

• a 300 mm facade is really narrow;

• there is a frame, panel, or vertical molding nearby;

• the handle should be a point accent;

• there are eight such facades on one furniture front;

• the entire wardrobe is built on the repetition of small details.

If the hand awkwardly catches a small Button, the mathematically beautiful proportion loses its meaning. Function is more important than a percentage table.

Button HL-036 53 mm on a 450 mm facade: about 11.8%

Average size:

53 / 450 × 100 = 11,8%.

Free space when centered:

(450 − 53) / 2 = 198.5 mm.

Let's compare with the first group:

• 37/300 = 12,3%;

• 53/450 = 11,8%.

The difference is only 0.5 percentage points.

This is exactly where you can see why a series of three sizes is stronger than one universal one.

The handle physically becomes larger by 16 mm, but the facade also expands by 150 mm. As a result, the relative visibility is almost preserved.

Size C of the 53-millimeter version is 27 mm, D is 18 mm.

Therefore, the average Button will feel different in hand than the small one. If the three groups of facades are used equally often, you need to check whether the change in grip is perceived as random.

Usually, the same shape softens this difference, but a real test is better than any assumption.

Button HL-036 74 mm on a 600 mm facade: again about 12.3%

Calculation:

74 / 600 × 100 = 12,3%.

Free field:

(600 − 74) / 2 = 263 mm.

This results in an almost mirror proportion to the 300 mm facade:

• 37 mm on 300 mm — 12.3%;

• 74 mm on 600 mm — 12.3%.

The facade became exactly twice as wide.

The handle is also twice as large in A:

74 / 37 = 2.

Therefore, the visual scale matches almost perfectly.

This is not a random artistic formulation, but direct geometry.

The large Button has C=29 mm and D=25 mm. It is deeper and protrudes more noticeably above the facade, so on a tall door it needs to be checked next to the adjacent leaf, the wardrobe trim, the mirror, and the walkway area.

Three facades and three buttons: a table of proportions

The spread of relative scale is only 0.5 percentage points.

This is the core of the design solution:

one model → three physical sizes → almost identical relative visibility.

If the wardrobe is built on widths of 300/450/600 mm, the Button HL-036 is especially convenient to use as a scalable system.

But percentage does not replace the layout. If the 600 mm facade is much taller, has a mirror, or other decor, the visual weight may change.

What happens if you put a 53 mm Button on all 24 facades

The average size often seems like a safe compromise.

Let's calculate:

53/300 = 17,7%;

53/450 = 11,8%;

53/600 = 8,8%.

That is, on a narrow facade, the handle is visually twice as active as on a large one.

If there is no such hierarchy in the project, the "average size for everyone" turns out to be not neutral, but a quite pronounced solution.

A procurement compromise is not equal to a design compromise.

When one Button size is still better than three

Mixing sizes does not need to be done automatically.

One size can be stronger if:

• facades differ little;

• all handles must form an absolutely identical physical rhythm;

• the project sets a single scale for the hardware;

• different groups of doors are located far from each other;

• grip matters more than relative proportion;

• the client wants to emphasize sameness, not scaling.

For example, if the facades are 420, 450, and 480 mm, switching to three different Buttons would be excessive.

In our 300/450/600 mm grid, the range is large enough for the 37/53/74 idea to make real sense.

How to order 24 Button HL-036 and not get 24 identical sizes

The working specification should split the batch into three lines.

The order should not include:

Button HL-036 — 24 pcs.

Such a line does not determine the size.

Correct:

Button HL-036 / 37×22×15 / beech / Prestige / 8 pcs.

Button HL-036 / 53×27×18 / beech / Prestige / 8 pcs.

Button HL-036 / 74×29×25 / beech / Prestige / 8 pcs.

Or the same three lines in oak.

If the designer chose a mixed material or a different quantity, the specification changes. But the size of each group must be fixed separately.

Project cost 8+8+8: beech and oak

For the current card:

Beech

8 × 750 = 6 000 ₽

8 × 1 020 = 8 160 ₽

8 × 1 260 = 10 080 ₽

Total:

24 240 ₽.

Oak

8 × 790 = 6 320 ₽

8 × 1 230 = 9 840 ₽

8 × 1 470 = 11 760 ₽

Total:

27 920 ₽.

Difference between a mixed batch of oak and beech:

27 920 − 24 240 = 3 680 ₽.

This is the cost of the handles themselves at the time of checking, without finishing, delivery, and additional work.

Prices change, so the card is reopened before payment.

How much would 24 identical Buttons of each size cost

For comparison, it's useful to see alternative baskets.

A mixed scheme of beech costs almost the same as 24 medium Buttons:

24,240 vs 24,480 ₽.

The difference is only 240 RUB.

This is an important commercial conclusion: scaling three groups does not necessarily mean a noticeable price increase compared to the "average size for all."

For oak, the mixed scheme is even cheaper than 24 average handles:

27,920 vs. 29,520 RUB.

That is, the decision can be made based on design and function, without fearing that three sizes will automatically make the order significantly more expensive.

Beech or oak: finish first, then wood species

Button HL-036 is available in beech and oak.

The choice of material cannot be reduced to the phrase "oak is better."

Beech

It is logical to consider for a covering enamel, especially if the facades are painted and the natural texture of the handle should not stand out.

Oak

Interesting with transparent or semi-transparent finishes, when the handle should remain wooden in perception.

But an oak Button on a painted MDF facade can be both a beautiful contrast and a random insert.

The decision depends on the entire wardrobe:

• is there an oak floor;

• is there veneer;

• what color are the facades;

• is metal present;

• is wood visible in other elements.

In the category you can buy wooden button handles and compare neighboring models, but for Button the material is still approved on a real sample.

Unpainted Button: why finishing should be decided before ordering

The card clearly states: Button HL-036 is supplied unpainted.

The base configuration is shown with preparation for enamel.

This means the buyer should not mentally consider the handle's price as the price of a finished colored product.

You need to decide:

• will there be an opaque enamel;

• will there be a transparent tint;

• is oak with visible texture needed;

• who performs the finishing;

• what gloss;

• how to maintain one shade across 24 handles;

• whether to paint the handles before installation;

• how to protect the attachment area.

If you need raw material for your own finishing system, you can buy unpainted wooden handles.

If the customer, on the contrary, needs ready-made hardware with an already applied coating, it makes more sense to compare the section buy furniture handles with coating, rather than ordering Button and then unexpectedly looking for a painting workshop.

Three sizes and one color: why the same paint code does not guarantee the same impression

37, 53, and 74 mm have different surface areas and depths.

Even with one color, a large Button catches more light.

A glossy or semi-gloss finish shows more:

• edge;

• convexity;

• shape transitions;

• Highlights on the surface.

A small 37-millimeter button may appear darker or calmer simply due to scale and light angle.

Therefore, a test sample should be viewed on two or three sizes at once if the project is sensitive to shade.

This is especially relevant for complex gray, green, burgundy, and almost black enamels.

Is it necessary to first order one Button as a sample?

If the workshop has already worked with HL-036 and has a physical sample of all three sizes, a separate trial purchase is not required.

If not, a sample is useful.

It allows you to check:

• real grip;

• finger position;

• size relative to the facade;

• shadow;

• surface after sanding;

• future paint finish;

• length of the complete fastening relative to the facade;

• proximity to the frame and mirror.

But there is a nuance: one 37 mm Button does not replace the 74 mm check.

If the project is based on three scales, it is better to get at least two extreme sizes — 37 and 74 mm. Then the range is immediately visible.

How to make paper templates without purchasing

For a frontal check, three circles or contours of size A are enough:

• 37 mm;

• 53 mm;

• 74 mm.

They are applied to facades of 300/450/600 mm.

It is useful to make not one template, but eight at once.

Then you can see the entire rhythm of the wardrobe:

• eight small;

• eight medium ones;

• eight large ones.

On screen, the idea 37/53/74 looks mathematically elegant.

On the full front, it will become clear whether there are too many large buttons or whether small ones get lost.

Center or edge: relative scale does not determine the handle position

In the article, we compare the handle's dimensions with the facade width.

But this does not mean that all buttons must be placed strictly in the center.

The handle can be located:

• along the vertical axis;

• closer to the door edge;

• on the common line of all facades;

• on the frame;

• on the panel;

• in the zone defined by the existing structure.

For a swing door, the handle is often shifted toward the opening side.

Then the formula (facade width − handle)/2 no longer describes the actual offset.

It remains useful only as an indicator of relative scale.

The position is set separately according to the project.

Position at the door edge: how to maintain rhythm with different facade widths

If the Button is not centered but near the vertical edge of a hinged door, the relative proportion of 12% remains useful, but a second parameter appears — the distance from the edge to the mounting axis.

Let's imagine three doors:

• 300 mm;

• 450 mm;

• 600 mm.

If on each door the handle is set back from the working edge by the same 55 mm to the center, the grip line becomes even, and the Button size scales separately.

This can give a more cohesive facade than trying to center the handle on each door.

In the working drawing, two decisions need to be separated:

the handle size and the coordinate of the mounting center.

They should not accidentally depend on each other.

For serial furniture, it is useful to set one baseline from the edge and then check how 37/53/74 mm protrude toward the frame, mirror, or panel.

Eight narrow drawers 300 mm: why the 37-millimeter Button must pass the grip test

On a small facade, 37 mm looks proportional.

But the drawer is not opened by sight.

A person must:

• bring fingers under;

• grip the button;

• pull toward themselves;

• not catch the adjacent facade;

• do not touch sharp edges or the frame.

Size A=37 mm does not indicate how comfortable it is for a specific user.

Therefore, one of the eight drawers needs to be fully assembled and checked:

1. empty drawer;

2. loaded drawer;

3. opening with one hand;

4. opening by two different users;

5. grip with gloves, if the dressing room is commercial and employees work in them;

6. no contact with the adjacent handle when opening simultaneously.

If 37 mm is visually ideal but functionally small, the project has the right to switch to 53 mm for narrow facades. Geometric proportion is a strong argument, but not an absolute rule.

Eight facades of 450 mm: why 53 mm is convenient to use as a control scale

The average facade and the average Button are almost in the middle of the entire system.

It is precisely them that are convenient to take as a reference.

First, on a 450 mm facade, determine:

• handle position;

• grip convenience;

• the height from the floor;

• connection with the panel;

• connection with the handles of neighboring cabinets;

• visual weight.

After approving the middle group, scale down and up.

If 53 mm on 450 mm really fits, then 37/300 and 74/600 give a similar relative result.

If 53 mm on 450 mm already seems too large, the entire proportional system should be reconsidered.

This is a good way to avoid drowning in 24 separate solutions.

Large doors 600 mm: when 74 mm looks right but interferes with the adjacent leaf

Button 74 mm has the greatest depth and physical volume.

On a 600 mm facade it is proportional, but large doors often have additional constraints:

• the door opens onto the adjacent section;

• there is a mirror nearby;

• there is a protruding trim;

• the leaves meet in pairs;

• the handles of two adjacent doors pass close together;

• In the passage, a person may catch their clothing on the hardware.

Therefore, a large Button needs to be checked not only on a closed door.

Open the leaf to the working angle and trace the trajectory.

If the handle passes close to a wall or another door, measure the minimum clearance.

Don't assume that just because the handle protrudes only 29 mm per parameter C, a conflict is ruled out. The actual geometry depends on the mounting location and the direction of the leaf's movement.

Mirror facades: why one template cannot be transferred automatically

In a walk-in closet, pairs of mirror doors are often found.

On the left one, the handle is at the right edge.

On the right one, it's at the left edge.

If you drill all facades using the same template without mirroring it, you can get an error.

Need at least two templates:

• L — for left doors;

• R — for right ones.

They fix:

• the top;

• bottom;

• working edge;

• hole center;

• Button size;

• group number 37/53/74.

Before drilling, the template is applied to one test door and the direction is checked.

This is especially important when there are 24 facades and three handle sizes in one dressing room at the same time: you can mix up not only the side, but also the size.

Code system for 24 facades: how not to mix up 37, 53, and 74 mm during installation

It is convenient to assign simple designations to groups:

• A37 — 8 facades of 300 mm;

• B53 — 8 facades of 450 mm;

• C74 — 8 facades of 600 mm.

Each facade receives a marking:

A37-01, A37-02 … A37-08;

B53-01 … B53-08;

C74-01 … C74-08.

This scheme solves several tasks at once:

• handles do not get mixed up;

• drilling templates are tied to the group;

• the painter knows that the entire batch belongs to one project;

• When accepting, it is easy to recount the set;

• When replacing a part, it is clear what size is needed.

For 24 handles of the same style, this is much more reliable than storing three loose sets of hardware in one box.

Fasteners are included in the price: what this means and what it does not mean

The Button HL-036 card indicates that the mounting kit is included in the price.

This is useful: the buyer does not receive a "bare" wooden button without the standard mounting set.

But it cannot be concluded from this that the kit automatically fits any facade thickness.

Before drilling, you need to check:

• the actual thickness of the door or drawer;

• the facade construction;

• length of standard fasteners;

• presence of pads;

• possibility of tightening;

• access to the reverse side;

• permissible hole diameter.

If the facade is unusually thick or has a multi-layer construction, the fastening issue is resolved before installation.

There is no need to replace the standard screw with a random longer one just because "a few millimeters are missing." Too long fasteners can damage the handle or go into the wrong area.

How to check the standard fastening on one facade before drilling the remaining 23

First, assemble a test unit.

Take one facade of the same thickness or a technological sample.

Next:

1. drill a hole according to the approved template;

2. install the complete fastening kit;

3. tighten without excessive force;

4. check for absence of play;

5. ensure that the fasteners do not protrude;

6. open the facade several dozen times;

7. remove the handle and inspect the condition of the hole;

8. only after this transfer the pattern to the series.

One test unit is cheaper than reworking 24 facades.

Beech Button under enamel: how to maintain one color across three sizes

If the wardrobe is painted in one solid color, beech looks like a logical candidate.

But all 24 handles must be perceived as one finishing batch.

The technical specification must include:

• one color code;

• one primer;

• one degree of gloss;

• the same number of layers;

• identical interlayer treatment;

• identical drying;

• one control sample.

Different sizes should not receive different processing modes just because 74 mm is larger.

At the same time, a large Button has more surface area, so the painter may intuitively apply the coat differently. This is exactly why a reference standard is needed.

Oak buttons for transparent finish: how to distribute wood across facades

If the handles remain wooden, four things become more noticeable:

• tone;

• direction of fibers;

• porosity;

• reaction to tinting.

For a batch of 8+8+8, it is useful to sort oak handles into groups before finishing.

For example, calmer patterns go on narrow drawers, more expressive ones on large doors. Or vice versa, if the project requires uniform intensity.

The main thing is to adopt the rule in advance.

You cannot discover after tinting that one large Button differs sharply from its neighbors and try to swap it with a small one: the sizes are different.

How much does one visual mistake in a group cost

Suppose after installing eight large 74 mm buttons, the client decides that 53 mm are needed on 600 mm doors after all.

The beech group 74 mm costs:

8 × 1 260 = 10 080 ₽.

New group 53 mm:

8 × 1 020 = 8 160 ₽.

Total:

18 240 ₽

without finishing, delivery, and labor.

For oak:

11 760 + 9 840 = 21 600 ₽.

Therefore, a paper template and one physical sample are not minor overcaution. This is a way to protect the budget.

Button or handle-staple: when point grip loses

A button handle is good where point grip is convenient and matches the design.

But there are situations where a staple is functionally stronger:

• a wide heavy drawer;

• facade that is often opened with two fingers in a hurry;

• door with high resistance of the door closer;

• the user needs a full-hand grip;

• two holes are already drilled;

• a long horizontal line is required.

If at least the last two points define the project, Button may be the wrong type.

In that case, it is better to buy furniture pull handles and re-check the design, rather than trying to make the button perform a function that isn't its own.

Button or wooden profile handle: the difference is not only in style

Button is a point element.

Profile is an extended grip line.

For a tall door of 600 mm or more, a profile handle may be more convenient if:

• the door is often opened;

• a grip at different heights is needed;

• the project requires almost invisible hardware;

• The facade is minimalist;

• a long line supports the cabinet architecture.

Then you can buy wooden profile handles and compare the functional scenario.

You don't need to choose Button just because it scales beautifully at 37/53/74 mm.

Button or surface-mounted handle: when a different mounting type is needed

A surface-mounted handle can have a larger contact area and a different grip character.

If the facade is thin, complex, or already has pre-drilled markings, the mounting type can become decisive.

Before making the final choice, you can buy furniture handle overlays and compare them with Button by:

• number of holes;

• depth;

• convenience;

• by size;

• finishing options;

• visual role.

But it's too late to change the handle type after drilling 24 facades.

When three Button sizes create a single rhythm, and when they create three different rhythms

The 12% proportion is a strong foundation, but not the only factor.

Three groups will be perceived as one if they match:

• the Button shape;

• color;

• material;

• installation height;

• Distance from the working edge;

• orientation;

• surrounding frame.

If 37 mm is centered on the drawer, 53 mm is at the edge of the door, and 74 mm is at a different height, the same percentage will no longer save unity.

Therefore, scaling only works within a common coordinate system.

How to build a common handle line across 24 facades

For a walk-in closet, the height placement is especially noticeable.

If handles are on doors and drawers of different heights, two approaches are possible.

In the center of each facade

Each Button is subordinate to its own element.

Plus — local symmetry.

Minus — the line across the entire wardrobe "jumps."

Along a common horizontal line

The centers of the handles align into one or several fixed lines.

Plus — a strong architectural system.

Minus — on some facades the handle is no longer centered.

The choice depends on the project.

Before drilling, it is useful to draw a common horizontal line with painter's tape across the entire wardrobe and temporarily place paper buttons.

Case with upper and lower drawers: one size of 37 mm may be better than two

If all 300-mm fronts belong to drawers, but their heights differ, it is not necessary to scale the handle also by height.

For example, the width of all is 300 mm, and the height:

• 120;

• 180;

• 240 mm.

The 37 mm button maintains one vertical rhythm across the width.

Switching to 53 mm only for a tall drawer may disrupt the system more than it helps.

In our article, scaling is tied to widths of 300/450/600 mm, not to all possible dimensions simultaneously.

What to do if the actual fronts are not 300/450/600, but 296/448/603 mm

Design figures need to be rechecked after manufacturing.

Let's calculate:

37/296 = 12,5%;

53/448 = 11,8%;

74/603 = 12,3%.

The system still remains close.

Minor production deviations do not ruin the idea.

But if one group is actually 520 mm instead of 450, the share of 53 mm is already:

53/520 = 10,2%.

Then it's worth checking again whether 74 mm is better.

Therefore, before finalizing the handle order, you need to take the actual facade list.

If the number of facades has changed: how to recalculate the order without confusion

Suppose after changing the project it becomes:

• 10 facades of 300 mm;

• 6 facades of 450 mm;

• 8 facades of 600 mm.

The total quantity is still 24, but the basket is different:

• 37 mm — 10 pcs.;

• 53 mm — 6 pcs.;

• 74 mm — 8 pcs.

You cannot keep the old 8+8+8 scheme just because the total count matches.

The commercial specification is built by actual groups, not by the total number of handles.

Warehouse check for the 8+8+8 scheme

At the time of the check in Saint Petersburg, the card shows:

Beech

• 37 mm — 123 pcs.;

• 53 mm — 108 pcs.;

• 74 mm — 86 pcs.

Oak

• 37 mm — 72 pcs.;

• 53 mm — 120 pcs.;

• 74 mm — 134 pcs.

For the current batch, each size has a sufficient published stock of eight pieces.

But this is not a reserve.

If the order is delayed, the data needs to be rechecked.

The warehouse figure exists for the decision "can we place it now," not for a long-term guarantee.

One batch or three separate orders

Technically, you can order:

• first 37 mm;

• then 53;

• then 74.

For one dressing room, this is rarely convenient.

Better one specification with three lines.

Why:

• single order date;

• single acceptance;

• one material;

• one finishing batch;

• one set of documentation;

• easier to control quantity;

• easier to check fasteners.

If some dimensions are missing, then it is decided whether to wait for the full batch or start work in stages.

Should we add one spare Button of each size?

The 1+1+1 reserve scheme will increase the order to 27 pieces.

For the beech, this will add:

750 + 1 020 + 1 260 = 3 030 ₽.

For oak:

790 + 1 230 + 1 470 = 3 490 ₽.

Such a reserve may be justified for a commercial facility if:

• the wardrobe is intensively used;

• the handles are painted in a complex custom color;

• replacement after a few years should be quick;

• storing three parts is convenient.

But the reserve cannot automatically be considered mandatory.

If the model is consistently available and the finish is simple, 24 pieces may be a sufficient order.

How to store the spare Button if the reserve is still purchased

The spare must be identifiable.

The packaging says:

Button HL-036 / 37×22×15 / material / color / date / project;

and similarly for 53 and 74 mm.

If the handles are painted, they must be stored so that the coating is not damaged.

After a few years, even a spare handle may differ from the installed furniture in perception, because the operational coating ages and changes its gloss.

But having the original part still greatly simplifies repairs.

How to make a mounting template for 24 facades and three Button sizes

Once the dimensions are approved, the next danger zone is drilling.

Each group needs its own template.

At least three:

• T37 for 300 mm facades;

• T53 for 450 mm fronts;

• T74 for 600 mm facades.

If there are mirrored doors, there may be six templates:

• T37-L;

• T37-R;

• T53-L;

• T53-R;

• T74-L;

• T74-R.

The template must include:

• top and bottom;

• working edge;

• hole axis;

• distance from edge;

• Button size code;

• template version number.

The last point seems like bureaucracy until the designer moves the handle by 5 mm after the first fitting.

The old template version must be destroyed or marked as invalid.

Why drill one facade of each group first, rather than all eight

Even a good drawing needs to be physically checked.

Correct sequence:

1. take one 300 mm facade;

2. install Button 37 mm;

3. check the grip and visual position;

4. repeat for 450/53;

5. repeat for 600/74;

6. place three test facades side by side;

7. only after approval drill the remaining 21.

This creates three control samples.

If after installation it turns out that 74 mm needs to be shifted 4 mm toward the edge, one facade is corrected, not eight.

Handle on a framed facade: count the width of the entire door or the inner panel

This is an important clarification.

In our main formula, Button is compared with the full width of the facade:

37/300, 53/450, 74/600.

But if the door is framed and the handle visually relates not to the entire door but to the narrow frame stile, then comparing it only with the total width may not be sufficient.

For example, a 600 mm door has a vertical stile 90 mm wide.

A 74 mm button on such a stile occupies:

74 / 90 × 100 = 82.2% of its width.

Although relative to the entire door, it is only 12.3%.

This is a completely different perception.

Therefore, for framed facades, it is necessary to determine which geometry the handle is attached to:

• to the entire leaf;

• to the frame stile;

• to the panel;

• to the central axis;

• to a separate decorative zone.

Only after this does the percentage scheme become correct
