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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e4″ Deck Plate with Standard Trim Ring\u003c\/li\u003e\n\u003cli\u003eOutside Diameter: 6 1\/8″ (15.6 cm) \u003c\/li\u003e\n\u003cli\u003eInside Diameter: 4″ (10.2 cm)\u003c\/li\u003e\n\u003cli\u003eHole Cut: 4 1\/2″ (11.4 cm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"color: #ff0000;\"\u003eSupporting safety and reliability aboard, Beckson screw-out deck plates in all sizes are now certified by independent lab testing to exceed FIVE certifications!
