Beckson 6" Clear Center Screw Out Deck Plate

The Beckson Screw-Out Plate was designed to provide access without using tools, with a single start, non-jamming (no cross-thread), and an extra strong, self-cleaning buttress thread. They incorporate a self-aligning center and an innovative gasket to ensure a watertight seal. A backup sealing wall leaves the plate watertight, even if the gasket is removed. Our clear center plates permit observation of controls or gauges and visual inspection without removing the center. Deck plates are used to access shut-off valves or back-fastenings, inspection, and clean-out for tanks and compartments. A screw-out plate should be used in compartments where a change in air pressure due to temperature or oil canning can occur.
