Screw-Out Deck Plate
Though deck plates are no new invention, Beckson was the first to conquer all three safety features and provide them here. First, ensure the cover would not open unexpectedly. Second, maintain 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 patented back-up sealing wall leaves the plate waterproof, 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.
Replacement O-ring gaskets are also available and sold separately
