Sea-Dog 3361401 Quarter-Turn Deck Plate, Smooth, 4-1/2" – White
Fast, tool-free deck access with a quarter-turn locking mechanism — open or close this plate with a simple 90-degree twist. The Sea-Dog 3361401 is the compact 4-1/2" option in the quarter-turn lineup, well-suited for smaller compartments on kayaks, canoes, and smaller powerboats. Built from injection-molded ABS/polycarbonate, it is UV-stabilized for long-term durability in harsh marine environments. A specially engineered lubricated gasket combined with a knife-edge seal delivers a leak-tested watertight closure every time.

Parts Desk Insights
Best use case: The 4-1/2" size is the right choice for smaller vessels and tighter compartments where a 5-1/2" or 6-1/2" plate would be too large — common on kayaks, canoes, and small fishing boats. The quarter-turn mechanism is the fastest-opening design in the Sea-Dog lineup, making it ideal for frequently accessed compartments like tackle storage and safety gear lockers. The white finish suits light-colored decks and hulls. For a larger opening in the same quarter-turn style, see the Sea-Dog 3361551 Quarter-Turn Deck Plate – 5-1/2" Black or the Sea-Dog 3361651 Quarter-Turn Deck Plate – 6-1/2" Black. For a screw-out style at a similar size, see the Sea-Dog 4" Screw-Out Deck Plate – White.
