Beckson twist-out watertight deck plates creates a watertight hatch to access voids. The circular hatch is watertight and secures easily with a twist. The 5" Deck Plate is designed to conceal its mounting fasteners under the wide flange of the quick twist cover. The low profile cover is self-centering, and quickly locks in place with a 1/8 twist.

Three separate sealing areas, each designed to chase water away from the plate opening, assure a watertight closure. The bayonet threads are non-jamming, self-cleaning and lift the center for easy removal.
