Boat and RV owners, this YaeMarine access hatch is seriously heavy-duty quality! Made from non-corrosion UV-stabilized ABS plastic, it can handle seriously tough marine environments without deteriorating. The low profile design only protrudes 0.7 inches above deck with 1 inch intrusion below, giving you a clean, flush finish that looks professional. The rubber seal ensures complete weatherproofing, which is crucial when you're dealing with water exposure. The lid hinges a full 180 degrees and completely covers the mounting flange - no ugly gaps or exposed edges. The strong recessed handles make opening easy, and the pre-drilled countersunk fastening holes simplify installation (though you'll need to provide your own mounting screws). Measuring 17-1/4 by 12-3/8 inches, it's the perfect size for most access needs on boats, caravans, or RVs. Whether you're replacing an old worn-out hatch or adding new access points, this hatch delivers that professional marine-grade quality without the crazy prices you often see in marine supply stores. The black color looks sharp and maintains its appearance thanks to the UV stabilization. It's one of those components that just works perfectly and lasts for years, making your life on the water so much easier!
