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.
