Tight-Grip Push-In Bumpers

A ridge on the stem provides a tighter grip than other push-in bumpers. Push the stem into a hole for quick installation. These bumpers are commonly used as feet on instruments and bench-top equipment to keep them from sliding. They're also good as spacers between sheets of material. Also known as stem and grommet bumpers.

Compressible-Stem Push-In Bumpers

The stem on these bumpers compresses to fit into tight holes. Push the stem into a hole for quick installation. These bumpers are commonly used as feet on instruments and bench-top equipment to keep them from sliding. They're also good as spacers between sheets of material. Also known as stem and grommet bumpers.

Heavy Duty Unthreaded Bumpers

All of these bumpers are reinforced with an embedded washer or base plate for strength. Often used as feet, spacers, and vibration dampers, they absorb shock to prevent damage to equipment and surfaces. They're also good for starting and stopping motion on automated machines. Install them with screws.

Unthreaded Bumpers

Install these bumpers with screws. Often used as feet, spacers, and vibration dampers, they absorb shock to prevent damage to equipment and surfaces.

Load-Rated Unthreaded Bumpers

Select these bumpers for applications that require specific load capacities. Often used as feet, spacers, and vibration dampers, they absorb shock to prevent damage to equipment and surfaces. They're also good for starting and stopping motion on automated machines and conveyors. Install them with a screw.

Angle Bumpers

These bumpers are at a 90° angle to protect corners on equipment, walls, and docks from damage caused by carts, vehicles, and other moving objects. Install them with screws.

Threaded-Stud Bumpers
