No need for screws, glue, rivets or holes of any kind. Pressure-sensitive adhesive allows them to be applied quickly and easily wherever protection is needed against nicks, scratches, scuffs, vibration, slippage or noise. And once applied Bumpon protectors stay applied . . . because they're backed by more than 50 years of 3M leader- ship in adhesives technology. Durable Bumpon protectors come in 6 standard shapes: Transparent, Hemisphere, Cylindrical, Tapered Square, Other Shapes and Bumpon Resilient Rollstock.
