    Features:

    • 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
