Sea-Dog Quarter-Turn Textured Deck Plate w/Internal Collar - White - 6"

The Sea-Dog Quarter-Turn Textured Deck Plate with Internal Collar in white is a marine-grade access fitting designed for serious boaters who demand reliable, corrosion-resistant hardware on their vessels. After years of running boats in saltwater and freshwater environments, any experienced angler knows that deck plates are the workhorses of boat maintenance—they provide secure access to through-hull fittings, storage compartments, and critical bilge systems without compromising the integrity of your hull. This 6-inch quarter-turn design eliminates the need for tools, allowing quick one-handed access when you need it most, whether you're checking on plumbing, electrical conduits, or emergency equipment.

Built by Sea-Dog, a trusted name in marine hardware, this deck plate features a textured finish that reduces slip hazards on wet decks—critical when you're moving around a rocking boat or during rough-water operations. The internal collar design ensures a watertight seal that holds up under pressure changes and constant thermal cycling from sun exposure. The quarter-turn locking mechanism is straightforward and durable; it requires only a 90-degree rotation to secure or release, and the white powder-coated finish resists UV degradation and salt spray better than bare aluminum, maintaining its appearance through years of marine service.

This 6-inch plate is ideal for cruising sailboats, center console fishing boats, and cabin cruisers where deck space is managed carefully and plumbing runs are standard. Installation is straightforward on decks with through-hull penetrations; the internal collar seats securely and the textured surface prevents accidental rotation from foot traffic. Whether you're maintaining a weekend runabout or a serious offshore vessel, this Sea-Dog quarter-turn deck plate delivers the reliability and corrosion resistance that keeps your boat running safely season after season.
