Though deck plates are no new invention, Beckson was the first to conquer all three safety features. First, a cover that would not open unexpectedly. Second, maximum water tightness. Third, prevent jamming closed or cross- threading that would prevent a cover from being closed.
The Beckson Screw-Out Plate was designed to provide access without the use of tools, with a single start, non-jamming (no cross-thread), extra strong, self-cleaning buttress thread. They incorporate a self-aligning center and an innovative gasket to assure a watertight seal. A unique back-up sealing wall leaves the plate water resistant, even if the gasket is removed.
A screw-out plate should be used in compartments where a change in air pressure due to temperature or oil canning can occur. Deck plates also are used for access, inspection, and clean out for tanks and compartments, or just as a general access for shut-off valves or back- fastenings. Our clear center plates permit observation of controls or gauges and visual inspection without the necessity of removing the plate.
Supporting safety and reliability aboard, Beckson pry-out and screw-out deck plates in all sizes are now certified by independent lab testing to exceed FIVE certifications! ABYC H-3 Watertightness, ABYC H-4, NEMA 250 6P Submergence, ISO 12216, ISO 11812

A note about fuel tank mounting.
We do NOT recommend your using our deck plates for access directly into a fuel tank.
Through the deck above the tank? OK. But into the tank itself? No.
The diesel fuel would “eat up” the molded o-ring over time and would allow fuel to leak – a totally unacceptable situation. You are better off using an aluminum or stainless steel plate and a diesel-compatible gasket material, attaching this plate onto the tank with through-bolt fasteners.
OEM Note: Specials color/materials and logo centers are available.
