The SEAFLO 02-Series 4" Marine Circular Deck Plate is engineered for superior performance in harsh saltwater environments. Constructed from UV-stabilized polypropylene, this hatch resists fading, cracking, and corrosion. The detachable screw-out lid offers quick access to below-deck areas, while the non-slip surface ensures safety on wet decks. Built to outperform earlier SEAFLO 01-Series models, this deck plate offers enhanced UV resistance and a stronger seal against water intrusion. The rotary locking system delivers a secure, watertight closure without tools. It's designed to mount flush on either vertical or horizontal surfaces, making it ideal for deck storage access or inspection ports. Installation is simple with pre-drilled holes for standard marine hardware. The heavy-duty lid and durable rubber gasket combine to provide long-lasting, watertight protection. Whether you're retrofitting a small sailboat or adding utility access to a powerboat, this hatch is backed by SEAFLO's 4-Year Limited Warranty for added peace of mind.
