Beckson Screw-Out Deck Plate

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.
