Product Overview
Custom rubber mount feet for chair leg applications can be developed with material options such as EPDM, SBR or an appropriate FKM formulation. Choose the finished compound for the floor surface, cleaning products and handling conditions. Material names should remain associated with the actual part specification rather than treated as interchangeable labels.
The leg attachment and working base need to fit independently of that selection. Check the height and contact angle with the complete chair resting as intended. A replacement material should be evaluated in the assembled geometry, particularly if its deformation changes how several feet share support.
Keep grit away from the underside and inspect for wear or movement at the leg end. During replacement, compare the internal profile and base shape as well as color. If one foot repeatedly wears at an edge, review the chair's contact angle and support arrangement before changing compound. A material upgrade should address a defined requirement rather than compensate for a foot that does not fit its mounting or floor position.
- Material options
- Custom EPDM or FKM or SBR formulation; tailor the geometry and color to the required interface and exposure.
- Hardness range
- 30–90 Shore A for rubber. Compare firmness under load at the intended contact face. The leg attachment and working base need to fit independently of that selection.
- Custom profile & fit
- Check the height and contact angle with the complete chair resting as intended.
- Assembly considerations
- A material upgrade should address a defined requirement rather than compensate for a foot that does not fit its mounting or floor position.
- Design check
- Keep grit away from the underside and inspect for wear or movement at the leg end.
Photos illustrate structure or material only. If one foot repeatedly wears at an edge, review the chair's contact angle and support arrangement before changing compound. ETOL directly manufactures custom-shaped silicone and rubber parts to your requirements.
