Cork Rubber—These bumpers combine the cushioning of cork with the durability and shock absorption of rubber. They'll absorb the heavy knocks of a cabinet door without scuffing or scratching it.

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.
