The specification only listed 104×102 mm: how to buy the wooden cornice KZ-002 and not replace it with KZ-001 with the same external dimension

The work sheet has a short line: "wooden cornice 104×102 mm". The designer believes this is enough: the profile is already selected, the builders know the room, and the purchaser just needs to order the required quantity. The problem appears at the time of purchase. STAVROS has at least two different cornices with the same first parameters — A=104 and C=102 mm. For KZ-002, the full profile is specified as 104×102×23×7 mm, and for KZ-001 — 104×102×24×17 mm.

That is, the entry "104×102" does not identify KZ-002. Based on the first two digits, you can select a different item that formally looks like "the same size" but has a different profile geometry. The discrepancy is especially noticeable in E: for KZ-002 it is 7 mm, for KZ-001 — 17 mm.

Therefore, for a new order, you need not an abbreviated entry but a full product line: KZ-002 + A×C×D×E + material + length L + quantity. If only 104×102 mm remains in the invoice or estimate, it is better to stop payment and request clarification without declaring the product incorrect in advance.

The specific profile can be checked as Wooden Cornice KZ-002. If the model has already been approved by the designer, it is the KZ-002 item that should be the first line of the purchasing specification.

Wooden cornice KZ-002: full size — 104×102×23×7 mm, not just 104×102

The current KZ-002 card shows five product lines.

Material	A×C×D×E×L, mm	Sanding	Price
MDF	104×102×23×7×2600	Prestige	2 460 ₽
Beech	104×102×23×7×2000	Prestige	6 950 ₽
Oak	104×102×23×7×2000	Prestige	10 290 ₽
Beech	104×102×23×7×2400	Prestige	8 600 ₽
Oak	104×102×23×7×2400	Prestige	12 660 ₽

For the MDF configuration selected on the card, the "Under enamel" preparation is also indicated. If available, the item is shipped from the warehouse within three working days; the average production time for an out-of-stock item is 5–10 days.

The main thing for this article is not the price itself, but the structure of the entry:

A=104 C=102 D=23 E=7 L=2000 / 2400 / 2600 depending on the material.

The first two parameters match KZ-001, but D and E do not.

Therefore, the line:

KZ-002 / 104×102

is weaker than:

KZ-002 / 104×102×23×7×2400 / oak / Prestige / quantity ___.

In the second entry, the profile and the specific purchase length are defined much more precisely.

Wooden cornice 104×102 mm has already been found — why this is still not enough

Searching by two digits creates a false sense of precision.

The user enters:

cornice 104×102

and gets a product that matches the first dimensions. At this stage, it's easy to decide that differences between adjacent SKUs are decorative and unimportant.

But molding cannot be bought like a board based only on width and height.

A specific architectural profile has:

• article number;
• A;
• C;
• D;
• E;
• the material;
• length L;
• finish.

If the designer has already chosen KZ-002, the buyer's task is not to re-select a "similar cornice." The specific specification needs to be reproduced.

Therefore, before buy wooden cornices, it is useful to first record the article number, and only then move on to the material and length.

KZ-002 and KZ-001 have 104×102 mm: where the similarity ends

This article does not compare two curtain rods as design alternatives. KZ-002 has already been chosen. KZ-001 is needed only as a clear demonstration that the first two digits do not identify the profile.

Parameter	KZ-002	KZ-001
A	104 мм	104 мм
C	102 мм	102 мм
D	23 мм	24 мм
E	7 мм	17 мм

Difference in D:

24 − 23 = 1 mm.

Difference by E:

17 − 7 = 10 mm.

At the same time, one cannot independently assign physical functions to D and E based on a photograph. For a project, their meaning and position need to be looked at in the drawings of specific products.

The commercial conclusion is simpler:

104×102 ≠ the same curtain rod.

If the invoice contains only these two digits, the article number and the full profile must be confirmed before payment.

Why D=23 and E=7 cannot be dropped from the KZ-002 specification

If the manufacturer has placed D and E into separate dimensional parameters, they are part of the profile identification.

The purchaser is not obliged to explain to the builder which specific part of the silhouette each of them forms. But they are obliged not to lose these values when transferring the item from the card to the estimate.

Correct line:

KZ-002 / 104×102×23×7 mm

Incomplete:

cornice 104×102 mm

This is especially important if the project passes through several hands:

1. the designer selects the product;
2. the specifier transfers it to Excel;
3. the estimator shortens the description;
4. the manager generates the invoice;
5. The installer receives the final statement.

At each stage, there is a risk that the article number will disappear, leaving only two digits.

Therefore, the full size is not a redundant technical detail, but protection against product substitution.

Material KZ-002 also determines the product length.

After confirming the profile, you need to select a material.

KZ-002 is available in MDF, beech, and oak.

Product lengths differ:

MDF (740–760 kg/m³, emission class E1/E0) provides ideal geometry, uniformity, and better base for enamel: high adhesion, smooth surface, absence of knots and cracks.

2600 mm.

Beech

2000 or 2400 mm.

Oak

2000 or 2400 mm.

Therefore, the line:

KZ-002 — 8 pcs.

is still insufficient.

Eight MDF products are 8×2600 mm.

Eight beech KZ-002 can be 8×2000 or 8×2400 mm.

The quantity is the same, but the total footage and cost are different.

Full purchasing logic:

first profile → then material → then L → then quantity.

How much do six KZ-002 cost: the price depends not only on the material, but also on the length

Suppose the project after cutting actually requires six identical strips of one SKU.

MDF 2600 mm

6 × 2 460 = 14 760 ₽.

Beech 2000 mm

6 × 6 950 = 41 700 ₽.

Beech 2400 mm

6 × 8 600 = 51 600 ₽.

Oak 2000 mm

6 × 10 290 = 61 740 ₽.

Oak 2400 mm

6 × 12 660 = 75 960 ₽.

These amounts cannot be used as a direct comparison of "which option is more profitable" without a cutting map. Different lengths give different total footage.

But for checking the invoice, arithmetic is useful. If a commercial proposal specifies six oak KZ-002 2400 mm, the buyer can quickly verify the product cost:

6 × 12,660 = 75,960 ₽ before delivery and other additional expenses.

KZ-002 2000, 2400, or 2600 mm: first choose the material, then calculate the quantity

Length does not exist separately from the material.

The working lines look like this:

KZ-002 / beech / 104×102×23×7×2000 mm

KZ-002 / oak / 104×102×23×7×2400 mm

KZ-002 / MDF / 104×102×23×7×2600 mm

After that, you can calculate the quantity based on the actual room lines.

You cannot first write "need 12 cornices" and then decide what length they will be. The number of slats is the result of cutting, not the first parameter of the purchase.

Why total footage doesn't replace a map of individual lines

Suppose a room has three walls requiring solid pieces of 1900 mm each.

Total length:

1900 + 1900 + 1900 = 5700 mm.

Simple arithmetic with 2400 mm:

5700 / 2400 = 2.375, meaning formally rounding gives three planks.

And indeed, three planks of 2400 mm give a gross total of 7200 mm.

But if the project consists of several separate sections with corner cuts, joints, or pattern constraints, each segment needs to be laid out across the original planks individually.

Therefore, in the purchase list, it's useful to store not only:

total footage of 5.7 m,

But also:

section A — 1900;
section B — 1900;
section C — 1900.

This helps verify whether the number of planks matches the actual cutting map.

The invoice states "104×102, oak, 6 pcs.": pay or request clarification

Such an item does not prove that the manager selected the wrong product.

But the identification is incomplete.

Before payment, you need to ask to add or confirm:

• KZ-002;
• D=23;
• E=7;
• length 2000 or 2400 mm;
• quantity.

Working wording:

Please confirm that the invoice specifies exactly KZ-002 with the full profile 104×102×23×7 mm and a length of ___ mm.

This is a normal commercial check, not a complaint.

After the response, the item changes from a "similar product" to a specific SKU.

How to check a commercial offer before payment

For KZ-002, it is enough to go through seven points.

Check	What should be included
Article number	KZ-002
A	104 мм
C	102 мм
D	23 мм
E	7 мм
Material	MDF / beech / oak
L	2600 / 2000 / 2400 mm for the selected SKU

Then check:

• quantity;
• price;
• availability or production time;
• delivery conditions;
• packaging.

The KZ-002 card indicates a rigid packaging frame costing 390 ₽. Packaging standards: MDF — up to 5 items, solid wood — up to 2 items. Therefore, for a large order, it is also useful to confirm the packaging line separately.

Why "buy wooden cornice" is just the beginning of the search

A commercial query may lead a buyer to the right category, but it does not replace a specification.

A person searches for "buy wooden cornice" or "wooden cornice buy", opens the catalog, and sees dozens of profiles.

For a general selection, this is normal.

But after the designer approved KZ-002, the search task ended. Next comes the configuration.

You need to move from a general request to a specific one:

KZ-002 / material / 104×102×23×7×L / quantity.

If you want to check the entire assortment, you can Buy wooden cornices through a specialized category, but an approved article should not be replaced with a neighboring one just because the first dimensions match.

MDF KZ-002 and solid wood KZ-002: the same profile does not mean the same purchasing line.

For KZ-002, the profile 104×102×23×7 is preserved, but the material and length change.

MDF:

104×102×23×7×2600.

Beech and oak:

104×102×23×7×2000;

or

104×102×23×7×2400.

This is important for projects where the designer only writes:

KZ-002 — 35 m.

This footage doesn't indicate how many planks to buy until the material is determined.

Moreover, MDF and solid wood cannot be automatically mixed in one line just for more convenient cutting. These are different materials, and such a substitution must be a separate design decision.

KZ-002 "Prestige": we also keep sanding in the order

The current KZ-002 card shows "Prestige" sanding.

Therefore, it's useful to keep this parameter in the purchase line:

KZ-002 / oak / 104×102×23×7×2400 / Prestige / quantity ___

It cannot be replaced with "Standard" without confirmation just for cost savings, if such a finish is not shown in the current product line.

For the selected MDF, the card also shows "Under enamel". This is blank preparation, not already applied white or colored enamel.

Buy wood molding together with KZ-002: we also record the adjacent trim in full

One of the reasons for errors is the different level of detail in one list.

For example:

KZ-002 / 104×102×23×7×2400

and below:

wooden molding 30 mm.

The first position is identified, the second — barely.

If the project includes wall molding, it should be recorded using the same principle:

article number + full profile + material + length + quantity.

To select adjacent linear elements, you can Buy wooden molding through the general section, but the final estimate should contain the specific product.

Buy wooden baseboard: the same mistake is easy to repeat at the bottom of the wall

Abbreviated specifications are not only for ceiling cornices.

Line:

wooden baseboard 120 mm

may also prove insufficient.

Specific skirting boards have their own:

• article numbers;
• profiles;
• thicknesses;
• materials;
• lengths.

Therefore, the discipline we use for KZ-002 is useful for all trim profiles.

If the project needs a lower contour, you can buy a wooden baseboard through the general catalog, and then transfer the specific SKU to the list.

Thus, one article does not turn into a review of skirting boards, but helps avoid the same type of purchasing mistake.

What to send to the STAVROS manager if KZ-002 is already approved

Ready template:

Product: KZ-002
Material: ___
Size A×C×D×E×L: 104×102×23×7×___ mm
Sanding: Prestige
Preparation: ___
Quantity: ___ pcs.
Delivery: ___
Please confirm the current price, availability, and the full product line in the invoice.

For MDF:

KZ-002 / MDF / 104×102×23×7×2600 mm / Prestige / For enamel / ___ pcs.

For oak 2400:

KZ-002 / oak / 104×102×23×7×2400 mm / Prestige / ___ pcs.

Such a request is easier to verify for both the manager and the buyer.

Acceptance of KZ-002 after delivery: we check not only the first 104×102

If during acceptance you open the old list "cornice 104×102", you might miss an error.

At the site, you need to verify the order against the confirmed specification:

• KZ-002;
• the material;
• D=23;
• E=7;
• length;
• quantity;
• condition of the packaging.

If the label or documents again show only 104×102, you need to raise the confirmed invoice or order.

It is especially useful to save the final specification together with the installation list, so that the installer does not replace one plank with a "same 104×102" from another batch or another article.

How to fix KZ-002 in the project so that 104×102 does not become the only marking again

After agreeing on the product, it is useful to correct not only the procurement list, but also all documents where the cornice is mentioned further down the chain.

For example, in the design project leave a line:

KZ-002 / profile 104×102×23×7 mm / material ___ / L ___ mm.

In the estimate — the same line plus quantity and price.

In the installation list — the same article number and full profile, but already linked to rooms and segments.

In the supplier's invoice — article number, material, length, and quantity.

So four documents refer to the same product.

Bad practice looks different:

design project — KZ-002;
estimate — cornice 104×102;
invoice — oak cornice;
installation list — ceiling profile 104 mm.

Each line individually seems clear, but together they lose the product's identity.

For an object with multiple rooms, it is also useful to mark the card check date. For example:

KZ-002 / checked 08.09.2026 / 104×102×23×7×2400 / oak.

The date is not a product characteristic, but it helps to understand which version of the product card the purchase was based on if the project is stretched over several months.

Packaging frame KZ-002: why its cost is better to see before payment

The current card KZ-002 indicates a rigid packaging frame costing 390 ₽.

The configuration standard is also specified:

• MDF — up to 5 items per frame;
• solid wood — up to 2 items per frame.

This allows for a preliminary check of the logistics line.

If the project needs six KZ-002 from the array and packaging is formed according to the specified rate of up to two items per frame, three frames will be required:

6 / 2 = 3 frames.

Preliminary cost:

3 × 390 = 1 170 ₽.

For six MDF items at a rate of up to five pieces, at least two frames will be required:

2 × 390 = 780 ₽.

This is a calculation based on the current card rate, not a promise of the final packaging amount for any order. Before payment, the specific number of frames must be confirmed in the invoice.

Such a block is especially useful when a buyer compares a commercial offer with the product cost and sees an additional 390, 780, or 1,170 rubles. This money does not mean that the seller "added an unknown item": for KZ-002, the packaging frame is directly provided by the card.

One batch of KZ-002 for multiple rooms: do not mix lengths without a specification sheet

Let's imagine that the oak KZ-002 is needed in the office, bedroom, and hallway.

For some lines, cutting is made from 2000 mm, for others 2400 mm is more convenient.

In the overall estimate, this cannot be reduced to a line:

KZ-002 oak — 18 pcs.

Better to split:

KZ-002 / oak / 104×102×23×7×2000 — ___ pcs.

KZ-002 / oak / 104×102×23×7×2400 — ___ pcs.

And then, within the installation map, distribute these two groups among the rooms.

Otherwise, on site, the master sees one common stack of identical profiles and starts cutting 2400-millimeter strips where 2000 were planned in the cutting layout, and short blanks remain for areas where the length is already insufficient.

That is, even after correct identification of KZ-002, procurement discipline does not end: length L remains an independent parameter of each item.

When KZ-002 does not need to be paid yet

It is better to pause the order until clarification if:

• only 104×102 mm remain in the list;
• the invoice has no article number;
• D and E are missing;
• material is not specified;
• length is not selected;
• quantity is calculated before determining the SKU length;
• the contractor proposes to replace KZ-002 with another 104×102 without approval;
• the project mixes different versions of the specification.

This does not mean that the product is necessarily selected incorrectly.

It means only one thing: there is not enough data for confident payment.

Errors when ordering KZ-002

Error: consider 104×102 a unique size. KZ-001 has the same A and C.

Error: lose D=23 and E=7. The profile ceases to be fully identified.

Error: write only KZ-002 without length. For the array there are 2000 and 2400 mm, for MDF — 2600 mm.

Error: count the quantity before choosing the material. The material determines the available length.

Error: mistake KZ-001 for KZ-002 due to the first dimensions. KZ-001 has D=24 and E=17.

Error: pay an invoice with an incomplete line without clarification. Better ask the manager to confirm the full SKU.

Error: replace the material for convenient cutting without approval. MDF, beech, and oak are different design solutions.

If KZ-001 suddenly appears in the invoice instead of KZ-002

Such a replacement cannot be accepted as technically equivalent just because the first parameters 104×102 match.

Need to return the invoice to the manager and clarify the reason for the replacement. Perhaps it is a simple error in the article number; perhaps KZ-001 was proposed as an available alternative. In both cases, the decision must be confirmed by the designer or another person responsible for the project.

To check, it is enough to compare the full string:

KZ-002 — 104×102×23×7 mm.

KZ-001 — 104×102×24×17 mm.

If the project is approved for KZ-002, paying for KZ-001 as "the same cornice 104×102" is not appropriate. First, you need to understand whether the replacement is acceptable according to the drawing, joints, adjacent elements, and the entire architectural line.

The same rule works in the opposite direction: the article does not claim that KZ-001 is worse or better. It is simply a different product. The buyer's task is to preserve the approved item number, not to choose between profiles at the time of invoice payment.

How to buy KZ-002 and not get "almost the same": final check

Before payment, you can go through a short decision tree.

Is only 104×102 in the bill of quantities?

→ Not enough.

Is the item number KZ-002 specified?

→ Checking the full profile.

D=23 and E=7?

→ Yes, the profile matches KZ-002.

Material selected?

→ Checking the available length.

Beech or oak?

→ 2000 or 2400 mm.

MDF?

→ 2600 mm.

Is L specified in the invoice?

→ Checking the quantity and price.

Do all fields match?

→ The order can be confirmed.

For additional assortment verification, you can buy wooden cornices, and if KZ-002 is already selected, return to its card and place an order for a specific SKU.
