Product Overview

Rubber caps for chair legs cover the ends with a custom molded contact layer. The internal socket should follow the receiving leg, while the base meets the floor in the chair's normal stance. The insertion depth matters as much as the width of the leg at the opening.

Check whether the leg tapers or changes shape inside the cap. A tip can grip at its upper edge while stopping too early to support the base properly. The bottom profile also needs to suit any leg angle so the chair rests across the intended contact area.

Clean the leg end and remove sharp material before fitting. Seat the cap fully, then compare all feet on a level surface to check for rocking. Keep grit from collecting beneath the rubber during use. Inspect the tips after the chair has been moved, looking for splits, displacement, or wear near the hard leg end. Replace damaged parts with matching installed heights so the original stance is preserved.

Material options
Rubber compound options, customized alongside the profile and contact conditions.
Hardness selection
Solid rubber options: 30–90 Shore A. The insertion depth matters as much as the width of the leg at the opening.
Custom geometry
The bottom profile also needs to suit any leg angle so the chair rests across the intended contact area.
Fit evaluation
Seat the cap fully, then compare all feet on a level surface to check for rocking.
Color & OEM
Custom colors; OEM identification positioned outside closure contact surfaces.

Ordering this custom component

Can the shape be adjusted to my mating parts?

Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.

Which details should be agreed before tooling?

Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.

Can a sample help define the replacement?

A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.

How is the quotation for this part determined?

The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
