Create a secure seacock installation with these rigid backing blocks.
Flanged seacock installations improve with the use of a backing block between the valve flange and the hull. Each backing block size fits multiple seacock sizes. Backing blocks include threaded inserts that press into the hull side of each block, into the holes that match the seacock flange. The 1/2" thickness is rigid enough for a secure installation, but flexible enough to conform to minor hull curvature. Backing blocks will not absorb moisture.
NOTE: Seacock shown for illustration only (sold separately).
