    These bumpers absorb impact to protect equipment, walls, and floors from dents and scuffs. They're found everywhere from access panels to the bases of equipment. The rubber construction also stifles noise and absorbs vibration to prevent wear and tear to your machinery and nearby surfaces. No separate fasteners are needed—just twist them into a threaded hole.

    These bumpers absorb impact well enough for most applications. However, they're not for use outdoors and break down when exposed to oil and harsh chemicals.
    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 ensure they’ll bear the weight of your application, these bumpers support everything from a 50-pound saw to a 2,000-pound 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 life than all-rubber bumpers. Twist them onto a threaded stud on your equipment, or pair them with your own stud to create a custom-length bumper.
