Cork Shields | McMaster-Carr

Stick these bumpers onto glass and other surfaces that are too fragile or thin for fasteners. Their adhesive sticks to your surface without scratching or discoloring it. From spacers to sound dampeners, they have a wide range of uses. They’re comparable to Bumpon bumpers.

Style 1

Cork—Soft and nonabrasive, these bumpers won't scuff your surface or objects that knock into them. Use them on wood furniture, glass, and surfaces that scratch easily.

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.

Tapered Plugs

Cork

0 Holes

Don't worry about having the exact size you need on hand—these plugs are shaped to fit a range of diameters. Push in until they're snug to mask holes during coating and finishing.

Cork—The original plug material, cork is compressible and flexible for a tight fit. These plugs are also slightly porous to allow some gas exchange. They are a sustainable and biodegradable alternative to rubber.
