Seacock Backing Plate for Secure Through-Hull Installation

Description

Flanged seacock installation is improved with the use of a backing block between the valve flange and the hull.

• Each size fits multiple seacock sizes
• Press threaded inserts into the hull side of the backing block into the holes that match the seacock flange
• 1/2″ thickness is rigid enough for a secure installation but flexible enough to conform to minor hull curvature
• Will not swell or absorb moisture

34-BB2: Fits 1-1/4″ and 1-1/2″ seacocks, 5.38″ D
