722 Description

Short technical summary and product information.

Keystone Electronics 722 is a screw-mount cylindrical bumper molded from black Buna S rubber. The bumper measures 0.718" (18.2mm) in diameter and 0.437" (11.1mm) in thickness, with a recessed center shape. It is supplied as individual pieces for mounting with a #4 screw.

 

The recessed center includes a 0.250" (6.4mm) center hole and a 0.218" (5.5mm) counterbore that is 0.125" (3.2mm) deep, allowing flush mounting of #4 hardware. The counterbore accommodates the screw head while the rubber body provides vibration dampening and skid resistance.

 

This bumper is part of the Keystone bumpers, feet, pads, and grips hardware line. It is suitable for cushioning enclosures, protecting surfaces from scuffs, and providing non-slip support in electronic and industrial equipment. Black Buna S rubber offers resilient, wear-resistant performance in a compact cylindrical package.
