Tempress Screw-Out Deck Plate 8″, White

The Tempress Screw-Out Deck Plate keeps wiring runs, fuel lines, and plumbing connections accessible without compromising your decks watertight integrity. The threaded center cap threads down firmly against a compression O-ring, creating a weather-tight seal that holds up in spray, rain, and wave wash. The beveled-edge flange sits flush and clean against the deck surface, and the safety-texture top provides sure footing underfoot. Constructed from UV-stable, corrosion-resistant structural polymer, this deck plate is built to perform season after season in the marine environment.

Parts Desk Insights

Best use case: The preferred screw-out option for 8″ cutouts where a positive thread-lock closure is required. Best suited for bilge inspection ports, battery compartments, fuel sender access, and any below-deck location that sees regular servicing but needs a reliable seal between uses. The screw-out design is preferred over snap-fit closures when the installation is exposed to spray, rain, or wave wash on deck. For lighter-access applications where a snap-fit is sufficient, see the Tempress Pry-Out Deck Plate. For larger hatch openings, see the Tempress Access Hatch with Cam Latch, 11″ 15″.

Note: The 8″ dimension refers to the plate outside diameter, not the cutout size. Verify your cutout diameter before ordering.
