Beckson 4" Clear Center Screw Out Deck Plate - Black

The Beckson Marine 4 in. Screw-Out Deck Plate provides tool-free access to compartments, tanks, shut-off valves, back-fastenings, or inspection points. This version has a black plate with a clear center for viewing controls, gauges, or interior areas without removing the center section.

The screw-out design uses a single-start, non-jamming buttress thread with a self-aligning center. Its gasket and back-up sealing wall are designed to maintain a watertight seal, including when the gasket is removed.
