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

Size: 7.13″ Dia.

Fits: 2″ & 2-1/2″ Seacocks

Bolt: 3/8″ – 16″
