Product Overview

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 back-up 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 the necessity of removing the center. Deck plates are used for access to 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.

Expert Overview

The Beckson 4" Clear Center Screw-Out Deck Plate, part number DP40-W-C, is designed to provide tool-free access to enclosed compartments. This deck plate features a single-start, self-cleaning buttress thread to prevent cross-threading and ensure secure closure. Its self-aligning center and integrated gasket contribute to a watertight seal, further supported by a secondary sealing wall that maintains watertight integrity even if the primary gasket is displaced. The clear center allows for visual inspection of internal components, such as controls or gauges, without requiring the plate's removal. This product is suitable for applications requiring access to shut-off valves, back-fastenings, or for inspection and clean-out purposes in tanks and compartments. It is also recommended for use in areas where air pressure fluctuations due to temperature changes or 'oil canning' might occur.
