Deck Plate / Inspection Port
6-1/8" O.D. x 4" I.D.
Screw Out, White

Though deck plates are no new invention, Beckson was the first to conquer all three safety features. First, a cover that would not open unexpectedly. Second, maximum watertightness. 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.
