The GROCO Backing Block, part number BB-2, is a marine-grade component designed to facilitate the secure installation of 1-1/4" and 1-1/2" seacocks. This backing block is intended for IT hardware resellers and their business clients who require reliable marine equipment for specialized applications. Constructed from an environmentally friendly PVC foam, it offers a rigid 1/2" thickness for stable mounting while retaining sufficient flexibility to conform to slight hull curvatures. A key feature is its resistance to swelling and moisture absorption, ensuring long-term durability in marine environments. The design allows for the press-fitting of threaded brass inserts into pre-drilled holes, matching the seacock flange for a precise fit. This product addresses the need for a robust, non-absorbent mounting foundation, crucial for maintaining the integrity of through-hull fittings on marine vessels.
