    Groco's BB-Series Backing Blocks improve the installation of a flanged seacock by creating a more secure connection through press threaded inserts and a flexible design that conforms to minor hull curvature.

    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
    • Includes threaded inserts that press into the hull side of each block
    • 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

    Note: Backing block includes brass inserts; stainless steel bolts are recommended

    Specifications:

    • Select dimensions and seacock application
    • Thickness: 1/2"
