Sea-Dog Quarter-Turn Smooth Deck Plate w/Internal Collar - Black - 6"

The Sea-Dog Quarter-Turn Smooth Deck Plate with Internal Collar in Black is a marine-grade access solution designed for boaters and vessel owners who require reliable and corrosion-resistant deck hardware. This 6-inch deck plate is ideal for quick access to below-deck storage, plumbing, electrical systems, or through-hull penetrations, ensuring that structural integrity is maintained.

Featuring a quarter-turn mechanism, this deck plate allows for one-handed operation, even in rough seas, making it essential for captains needing fast access during critical moments. Constructed from heavy-duty marine-grade materials, it has a smooth, non-snagging surface that prevents catching lines, nets, or gear. The internal collar design ensures a watertight seal and allows the plate to sit flush with the deck, minimizing trip hazards and water pooling.

This 6-inch deck plate is compatible with standard through-deck installations on fiberglass, composite, and reinforced deck surfaces. Installation is straightforward—simply cut a matching opening, insert the collar from below, and secure from above using the provided fasteners. The black finish resists UV damage and blends seamlessly with modern deck aesthetics while providing superior corrosion resistance in both saltwater and freshwater environments.
