Support the shelf; identify the host interface
A cabinet shelf support presents a bearing surface beneath a shelf and locates in, or attaches to, a cabinet side. Its insertion pin and supporting surface serve different functions from an industrial locating dowel. Identify both sides of the interface rather than ordering by pin diameter alone.
Compare construction choices
| Selection field | What to identify |
|---|---|
| Push-in peg | Insertion pin, shoulder, bearing projection and cabinet-hole geometry. |
| Peg with separate sleeve | Define the sleeve and peg as matched parts; identify the host bore and insertion interface separately. |
| Threaded or attached support | State the selected thread or attachment construction, receiving material and drawing. A smooth peg is not a screw-in substitute. |
| Shelf-contact surface | Flat, shaped or padded contact as specified. Glass contact requires the selected protective interface; a bare metal peg is not an automatic equivalent. |
Cabinet and shelf inputs
Send cabinet and shelf materials, thicknesses, edge details, hole dimensions, support locations, bearing projection and any sleeve or protective pad. Identify the required removable, retained or other selected construction explicitly. A plain support does not by itself establish lift-out protection.
Load and retention are not inferred from appearance
The responsible designer must define acceptance for the complete shelf and cabinet assembly, including the shelf, supports, substrate and support layout. This page does not prescribe support count, spacing, a shelf load or a pull-out rating. Manufacturer ratings for one catalogue item do not apply to a generic replacement.
Quotation checklist
| Selection field | What to identify |
|---|---|
| Component | Selected reference or drawing/revision; pin, shoulder, bearing face and any thread. |
| Host | Cabinet and shelf materials, host-hole drawing, sleeves, pads and mating clearances. |
| Acceptance | Buyer-defined assembly, retention, finish and inspection requirements with the responsible reviewer. |
| Order | Material, finish, quantity by variant, separate or paired accessories, packing and destination. |
Keep adjoining families distinct
- Industrial dowel pins locate mating machine parts; they are not a blanket shelf-support alternative.
- Furniture cam connectors capture a matched dowel to join prepared panels.
- Euro hinge and rail screws mount selected furniture hardware; their head and host interface need a separate specification.
Construction references
Manufacturer references identify construction and selection differences only. Brand names and system numbers are not generic standards, interchangeability, FastenerBridge affiliation or supply evidence. No catalogue dimensions, loads or installation prescriptions are transferred here.
Common selection questions
Is a shelf support the same as an industrial dowel pin?
No. A shelf support has a shelf-bearing interface and cabinet attachment requirements. A locating pin does not establish these functions.
Does matching the pin diameter confirm replacement fit?
No. Also identify the host hole, shoulder, projection, bearing surface, shelf material and any pad, sleeve or retention feature.
Is there a universal shelf load for these pegs?
No. The full assembly and selected product require buyer-approved acceptance. The generic illustration and this page do not establish a load rating.
