BACK BLOCK 1.25"-1.5" SEACOCK
Flanged seacock installation is improved with the use of a backing block between the valve flange and the hull. Size 5.38" Dia. Fits 1-1/4" & 1-1/2" Seacocks Bolt 5/16" - 18"
- 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.
