    Style 1

    Unlike our other adhesive-back bumpers, these are tested to ensure they'll support the load of your application. Use them as feet on instruments and small appliances to limit sliding, vibration, and noise. The adhesive back forms a tight grip without scratching or discoloring your surface. They're comparable to Bumpon bumpers.

    Ultra-Cushioning Sorbothane—Our softest bumpers have a feel that ranges from the softness of a gel insole to the firmness of a pencil eraser. They’re often used to cushion fragile materials. These bumpers boast shock-absorbing properties, making them a smart choice for mounting sensitive electronics.
    Hardness Rating—The harder the bumper, the better it withstands impact and abrasion over time. The softer the bumper, the more cushioning it provides for objects made of glass, soft metal, and other fragile materials. Bumpers with a medium rating offer a balance of impact resistance and cushioning.

    Tested to support the load of your application. These bumpers support a wide range of equipment—from a 50 lb. saw to a 5,000 lb. air compressor. They also help reduce vibration and protect whatever they’re mounted to. All have a metal base plate for added strength and a longer service life than all-rubber bumpers. No separate fasteners are needed—just twist them into a threaded hole.
