Geometric shape KN-007

Among the flat disc elements of the KN series, there is a fundamental difference between a "thin washer" and a "volumetric disc". KN-010 (height 23 mm, diameter 147 mm) is a maximally flat, horizontal part where width dominates. KN-007 (height 44 mm, diameter 120 mm) occupies a different niche: tall enough to have its own rounded profile, and wide enough to create a noticeable horizontal accent. It is not a ring or a sphere — it is a lenticular disc with a convex profile, combining volume and width in one part.

The size 44 × 120 × 120 mm creates a shape with a height-to-diameter ratio of 44/120 = 0.37. This proportion is well known from classical architectural bands: torus, ovolo, echinus — all of them represent exactly this shape: wide, but with a pronounced rounded profile. On a 34 mm diameter axis, the KN-007 disc creates precisely this effect — a "belt" or "roller" that is both a transitional element and an independent decorative accent.

Geometric shape KN-007 for furniture and interior structures

KN-007 is decorative part made of solid wood with a clearly expressed dual character: it is simultaneously tall enough to have its own volume, and wide enough to create a horizontal accent plane. In STAVROS constructor system with a single mounting diameter D 34 mm, KN-007 takes on the role of an "intermediate accent" — a part that is more noticeable than the compact rings KN-009 and KN-010, but does not dominate the structure like large spherical elements.

The main task that KN-007 solves: to create an expressive decorative node where you need neither a small wooden spacer nor a monumental ball, but something in between — a voluminous rounded shape with pronounced width, framing the transition, landing, or connection point.

The part is installed when the actual diameter of the supporting element matches the mounting hole D 34 mm. Before ordering, it is necessary to measure the diameter of the rod, post, or other axis and compare it with this value.

Three main roles of KN-007 in the structure

Decorative washer with volume. Unlike KN-010 (a thin flat disk 23 mm high), KN-007 has a height of 44 mm and a convex toroidal profile. This is not just a "washer" — it is a voluminous rounded shape that is perceived as an independent decorative element, not a spacer. On a 34 mm diameter axis, KN-007 looks like a "belt" or "roller" — a classic architectural motif.

Base or top of a post. At the base of a vertical post, KN-007 creates a "plinth" with pronounced volume: wide (120 mm), but not excessively high (44 mm), with a rounded profile that smoothly "receives" the vertical axis. This is a softer, more organic transition than the sharp edge of a flat disk.

Medium-sized separator between large elements. Between two ball elements of the KN-007 series, it works as an "intermediate belt" — wider than the compact ring KN-009, but significantly lower and wider than full-sized balls. This intermediate scale makes the structure multi-level: large ball — medium belt — large ball.

Where KN-007 is used: areas and scenarios

The 44 × 120 mm format opens up the same application areas for KN-007 as for other elements in the series, but with a special emphasis on medium-scale nodes where a voluminous rounded transition is needed.

Decorative rods: voluminous accent on the axis

wooden element for a rod A diameter of 120 mm on a rod with a diameter of 34 mm creates a pronounced "axis-belt" contrast: a thin horizontal rod with a wide rounded disk is perceived as a professionally designed decorative system. With a height of 44 mm, the disk is clearly visible not only from the side, but also from below or at an angle.

On a horizontal rod 800–1000 mm long, one central KN-007 creates a single powerful accent. Two KN-007s, positioned symmetrically, form a rhythmic pair with equal intervals from the center. In both cases, the rounded shape of the disk softly "breaks" the monotony of the straight rod without overloading the structure.

Furniture posts: rounded transition in vertical structure

On vertical wooden posts KN-007 works as a "roller" — one of the oldest architectural motifs. On a post 600–800 mm high, KN-007 occupies 44 mm of the 600–800 mm height — this is a significant, well-visible element, yet not overly large. On a post 1000–1200 mm high, one or two KN-007 create a rhythm of "belts" dividing the vertical structure.

KN-007 works especially organically in transitions between straight sections of the post and large spherical elements: the rounded profile of the disc "prepares" the eye for the volume of the sphere, creating a smooth rather than abrupt transition.

Furniture legs: voluminous "belt" on the leg

Wooden furniture leg with KN-007 at the base or in the central part receives a pronounced "belt" with a diameter of 120 mm. On a cabinet, console, or chair 350–450 mm high, this accent occupies about 10–12% of the leg height — enough for clear decorative division, but not so much as to overload.

In a composite leg made of several elements of the series, KN-007 takes the place of the central "belly" — wider and more voluminous than adjacent straight sections, but not as large as a sphere. This is a classic "turned leg" from historical furniture — with a characteristic bulge in the middle part.

Balusters and staircase structures

on wooden balusters for stairs KN-007 creates a "belt" — a medium-sized horizontal transition. With a height of 44 mm and a diameter of 120 mm on a baluster 900–1000 mm high, KN-007 occupies about 5% of the height: this is a delicate, proportionate accent that does not dominate the structure but clearly divides its vertical.

In complex balusters with several elements on the axis, KN-007 works as a "middle belt" — more noticeable than the thin ring KN-009, but significantly lighter than a large sphere. This allows building three-level hierarchies: large accent — middle belt — small ring — and so on in any sequence.

Wooden partitions and interior axes

On vertical rods of wooden partitions Decorative wooden disc with a diameter of 120 mm and a height of 44 mm creates an expressive "node" on the rod — noticeable but without disrupting the airy structure. This is a significantly more expressive accent than the thin ring KN-009, yet much lighter than a spherical element with a diameter of 130–170 mm.

Designer furniture: beds, consoles, chests of drawers

In designer pieces, KN-007 is a tool for creating decorative "belts" on posts and legs of any scale. On a bed with turned headboard posts, KN-007 creates an expressive accent in the central part of each post. On a console with wooden supports — a decorative base with a soft rounded profile. On a chest of drawers or nightstand with composite legs — a "belt" at the transition point from the support part to the decorative part.

Dimensions 44 × 120 × 120 mm and a 34 mm hole: the geometry of a lenticular disk

Parameter breakdown

A = 44 mm — height along the axis. 44 mm is twice as much as KN-009 (22 mm) and KN-010 (23 mm). At this height, the shape of the part is perceived not as a "thin plate" but as a "volumetric disk" with a pronounced convex profile. The eye registers not only the width but also the height of the element, giving it independent decorative value.

B = C = 120 mm — transverse dimension. A diameter of 120 mm is a significant width, ensuring good visibility of the element. The ring "wall" from the edge of the hole to the outer contour: (120 − 34) / 2 = 43 mm. At a height of 44 mm, these 43 mm of "wall" are sufficient to form a full convex toroidal profile.

D = 34 mm — mounting diameter, a unified standard of the KN series. All elements of the furniture construction kit Series are compatible on the same axis.

KN-007's place in the lineup: between a disk and a sphere

KN-007 and KN-009 have a similar A/B ratio (~0.37 and 0.35), but fundamentally different scale: KN-007 is four times larger in diameter. This determines different roles: KN-009 is an inconspicuous delicate separator, KN-007 is a noticeable voluminous "belt" of medium scale.

Rounded shape as a decorative transition

The rounded profile is the key difference between KN-007 and the flat discs of the series. Where KN-010 creates a sharp horizontal edge (a flat disc with even ends), KN-007 forms a smooth convex surface — a toroidal "roller", softly transitioning from the maximum diameter to the ends.

Softness of transition as a decorative principle

On the vertical axis, the rounded profile of KN-007 "softens" the structure: the straight lines of the post or rod are interrupted by a smooth convexity, and this transition is perceived as intentional, organic, "made by a master's hand" — and not as a technical joint. In classic furniture and architecture, it is rounded "rollers" and "tones" that are the most common transitional elements — precisely because the rounded shape fits most organically into any stylistic context.

Contrast of "axis — disc" as a decorative technique

On a thin axis with a diameter of 34–40 mm, the KN-007 disc with a diameter of 120 mm creates a pronounced contrast of scales: the axis is 3.5 times thinner than the disc. Wooden separator for rod with this ratio it is perceived as a "bead" — a classic decorative technique where a voluminous element strung on a thread creates an expressive accent. At the same time, the rounded profile of KN-007 makes this contrast soft and organic, rather than sharp.

Combination with other elements of the series

Unlike thin ring-shaped details, KN-007 provides more pronounced volume and participates more noticeably in the decorative composition — this makes it an ideal "middle level" in multi-tiered structures. Between a large sphere and a thin ring, KN-007 creates an intermediate accent, ensuring a smooth hierarchy of sizes: large — medium — small. Can be used together with other decorative elements made of solid wood STAVROS on the same principle.

Beech and oak: material on a rounded surface

On a convex toroidal surface with a diameter of 120 mm and a height of 44 mm, the material behaves differently than on a flat disk. The rounded shape "envelops" the light: the reflection glides over the convexity, creating a gradient from light to dark, which further emphasizes the volume.

Part made of solid beech for enamel

On the rounded surface of KN-007, beech under enamel creates a clean monochrome "roller" with a beautiful light reflection. The roundness of the shape makes the light "flow around" the part: on the convex top — a bright spot, on the side ends — a smooth darkening. This effect enhances the volume even at a height of only 44 mm. Beech part under enamel — a choice for modern interiors where the shape of the part should be sculpturally clean, without textural accents.

Solid oak part for tinting

On the convex surface of oak, the wood pattern creates a characteristic effect: radial fibers, bending around the toroidal shape, form an arched pattern that changes depending on the viewing angle. Oak part for tinting — a choice for projects where the natural texture of wood serves as a decorative tool. At a height of 44 mm and a diameter of 120 mm, the oak pattern is fully visible: this oak "roller" in dark walnut or honey creates a rich, natural accent.

The oak KN-007 works particularly organically in combination with metal: a brass flange, matte black rods, bronze elements. Warm wood on cold metal — a contrast that is one of the most sought-after in modern premium and luxury furniture.

"Prestige" sanding quality: smooth profile without tool marks

On a convex toroidal surface, tool marks appear as horizontal "rings" — fine scratches that become clearly visible when tinting or varnish is applied. At a diameter of 120 mm and with side lighting, these defects are noticeable from a distance of 1–2 meters.

"Prestige" quality for KN-007 means sequential finishing sanding of the curved convex surface with gradual grit reduction and final manual finishing — without horizontal scratches, without uneven removal in transition zones. Result: a smooth, clean profile ready for final coating without additional preparation.

For a rounded shape, clean processing of both ends of the part — the flat surfaces at the top and bottom of the disc — is also important. On furniture construction element in a composite structure, these ends adjoin adjacent parts and are clearly visible upon close inspection. "Prestige" quality ensures their flatness and cleanliness on par with the main convex surface.

KN-007 in the STAVROS system: combinations and schemes

Scheme "belt between balls"

KN-007 (diameter 120 mm, height 44 mm) between two balls KN-004 (diameter 170 mm) or KN-002 (diameter 132 mm) — a classic "ball — belt — ball" scheme. The middle element makes the structure three-part: two large accents separated by a wide horizontal belt. On a baluster or decorative post, this scheme creates a professional, finished look.

"Three belts" pattern

Three KN-007 at equal intervals on one axis — a rhythm of three identical "belts". On a vertical post 800–1000 mm high, this is a classic "three-tier" structure with clear horizontal division. On a horizontal rod, it is a symmetrical system of three accents dividing the rod into four equal sections.

"Hierarchy of three scales" pattern

KN-004 (sphere 170 mm) in the center, two KN-007 (disc 120 mm) on the sides, four KN-009 (ring 62 mm) as extreme dividers — a three-level hierarchy: large — medium — small. This pattern creates the richest, multi-level decorative structure with absolute geometric logic and predictability of the result. All elements of the constructor are compatible on a single axis D 34 mm.

Combination with other catalog sections

С with matching legs: KN-007 as the central "belly" of a composite leg — voluminous, wide, with a soft rounded profile. A leg with KN-007 in the center looks like a classic turned furniture leg with a characteristic bulge.

С balusters for staircases: KN-007 as one of several accent "belts" on a baluster. Combined with a larger sphere and several straight sections — a professional multi-part baluster.

С carved wooden decor: KN-007 as a geometric "roller" alternating with carved ornament on a single structure. Turned geometry and carved ornament from the same wood species create a rich, multi-level decorative program.

Who is KN-007 suitable for: audience and tasks

Furniture workshops and joinery productions. KN-007 is a ready-made "belt" element with precise dimensions and a high-quality surface, eliminating the need to manufacture toroidal transition parts on lathe equipment. In production, this saves setup and processing time with guaranteed quality of the result.

Interior designers. A round disc with a diameter of 120 mm is a predictable, standardized element included in the specification by article number. No custom turning work for the project — the part arrives exactly as intended.

Staircase manufacturers. On KN-007 balusters, it creates a medium-scale "belt" — noticeable enough to be read from a distance on a flight of stairs, but without overloading the structure. Compatible with all other elements of the KN series for creating complex multi-part wooden balusters.

Masters of wooden partitions. KN-007 on a vertical partition rod is a volumetric accent that gives the structure architectural character without compromising its lightness.

Restorers. Toroidal "rollers" and "belts" on supports are one of the most common motifs in classical and neoclassical furniture. KN-007 is suitable for recreating such elements or used as a base for manual refinement to match a specific historical sample.

Private customers. STAVROS accepts orders from a single piece. Full catalog of decorative elements made of solid available for private individuals without a minimum order quantity.

Frequently Asked Questions (FAQ)

What is the geometric shape KN-007 used for?

KN-007 is used as a decorative wooden part in the shape of a round disc for furniture and interior structures: designing bases of posts and legs, transitions on rods, "belts" on balusters, separators between volumetric elements, and decorative nodes in custom furniture. The diameter of 120 mm with a height of 44 mm creates an expressive volumetric accent.

Can KN-007 be used as a wooden washer?

Yes. In shape, KN-007 is a decorative wooden washer with a rounded convex profile and a mounting hole D 34 mm. The fundamental difference from the flat washer KN-010: the height of 44 mm gives KN-007 its own volume — it is not a thin plate, but a volumetric "roller". Before ordering, it is necessary to check the diameter of the supporting element against the 34 mm hole.

How does KN-007 differ from KN-010?

KN-007 (44 × 120 mm, proportion 0.37) is significantly taller than KN-010 (23 × 147 mm, proportion 0.16). KN-010 is a maximally flat wide disc, dominating the horizontal plane. KN-007 is a voluminous toroidal "roller" with a pronounced rounded profile, simultaneously wide and tall. Both elements are compatible on the same axis D 34 mm and combine well in a single design.

How does KN-007 differ from the compact rings KN-009?

KN-007 is four times wider (120 mm vs. 62 mm for KN-009) and twice as tall (44 mm vs. 22 mm). KN-009 is a delicate compact separator, almost invisible in a large structure. KN-007 is a noticeable voluminous "belt", fundamentally participating in the decorative composition. Both elements are compatible on a single axis and effectively combine in a "large — medium — small" scheme.

Is KN-007 suitable for a baluster or furniture leg?

Yes. On wooden baluster KN-007 creates a medium-scale "belt". On chair leg — the voluminous body of a composite leg with a characteristic "belly" of a classic turned shape. In both cases — when the mounting diameter of 34 mm matches.

What to choose — beech or oak for KN-007?

Beech — for enamel, when the rounded shape should be perceived as a pure sculptural volume with a beautiful light reflection without textural accents. Oak — for tinting, when the wood grain should be visible on the convex surface: radial fibers wrapping around the toroidal shape create a natural ornament, unique for each specimen.
