Beckson Marine 6" Non-Skid Pry-Out Deck Plate - White. These plates were designed with an extra heavy O-ring to assure a water tight fit. Plates are provided with non-skid or smooth surfaces for different installation requirements. The original was used to access the handle for Beckson's permanently mounted pump. The Beckson Diamond Pattern deck plate extends across the center eliminating a ring around the edge that traps dirt and debris. Pry-out plates should be installed in areas where internal pressure (oil-canning) is not present.
