The Dock Edge Stationary Galvanized Metal Dock Backer Plate helps keep your dock securely in place for years to come. Made of 1/8-inch thick hot dipped galvanized steel with holes for carriage bolts, it prevents the pipes and bolts from compressing into the wood and sliding down. The result is a stable dock that stands up to the wear and tear of heavy boats launching and landing.
