Perko 0526004PLB Deck Plates A deck plate that looks good and holds up to years of marine exposure is harder to find than it sounds — which is exactly why Perko's cast bronze deck plates have been a go-to choice for builders and boat owners who care about both function and finish. The Perko 0526004PLB is a 4" cast bronze deck plate available in plain or chrome-plated finish, giving you the flexibility to match your boat's hardware aesthetic without compromising on durability. Cast bronze construction sets this plate apart from lighter-duty alternatives. Bronze is naturally corrosion-resistant in both salt and freshwater environments, and the cast construction means it's solid and substantial — not stamped sheet metal that flexes under load or corrodes at the edges over time. At 4" in diameter, it's a versatile size that works well for fuel fills, water fills, storage access points, and other deck penetrations where a secure, watertight closure is needed. The deck plate key is included, so you have everything needed for installation and operation right out of the box. Note that an O-ring is not included — if your application requires a sealed closure, you'll want to source the appropriate O-ring separately to complete the installation. Specifications: Part Number: 0526004PLB Size: 4" diameter Material: Cast bronze Finish: Plain Deck plate key included O-ring not included Measure your existing deck opening or cutout before ordering to confirm the 4" size is the correct fit for your application. Perko produces deck plates in multiple sizes, so verifying the diameter upfront keeps the installation straightforward. Normalized SKU: 0526004PLBUPC Code: 085226193644

Sea-Dog 336411-1 Deck Plates The Sea-Dog 336411-1 is a 6-inch low-profile deck plate designed to provide convenient access to storage compartments, fuel fills, water tanks, and other below-deck areas while maintaining a clean, streamlined appearance on your boat's deck. The low-profile design sits nearly flush with the deck surface, reducing trip hazards and creating a sleeker look compared to traditional raised deck plates. Constructed from durable, UV-resistant black plastic, this deck plate is engineered to withstand the harsh marine environment, including constant exposure to saltwater, UV radiation, and temperature extremes. The black finish provides a professional appearance that complements most boat deck colors while resisting fading and discoloration over time. The 6-inch diameter provides ample opening size for accessing storage areas, filling tanks, or routing cables and hoses. The screw-out design features a threaded collar that secures the plate firmly in place while allowing easy removal when access is needed. The O-ring seal creates a watertight barrier that prevents water intrusion into storage compartments and below-deck areas, protecting your gear and equipment from moisture damage. The low-profile construction minimizes the plate's height above the deck surface, reducing the likelihood of stubbed toes or tripping hazards while maintaining full functionality. Installation is straightforward, requiring only a 6-inch hole saw to create the mounting opening. The threaded design ensures a secure, vibration-resistant fit that won't loosen over time from engine vibration or wave action. Whether you're installing new deck access points, replacing worn deck plates, or upgrading to a lower-profile design, this Sea-Dog deck plate provides reliable, watertight access with a clean, professional appearance.
