The Standard Faucet Knockout is a reusable silicone form used to create a 1-3/8" faucet hole in cast-in-place concrete countertops. It also forms a 2-1/2" mounting pocket positioned 1" below the surface, allowing room to fasten most standard faucet and spout hardware. Designed for use with 1/2" substrate and standard 2-1/4" Z Counterforms, this knockout helps simplify faucet placement and creates a clean, consistent opening during countertop forming.
