Lewmar Size 70 Medium Profile Flange Hatch, Grey Anodized Aluminum, Part 39970020

The Lewmar Size 70 Medium Profile Flange Hatch is a replacement deck hatch built for boats that need a durable, corrosion-resistant opening for light, ventilation, and access below deck. The frame is made from anodized aluminum, giving it strong resistance to the corrosive effects of saltwater and marine air so it holds up season after season. The lid is fitted with a seal and acrylic pane set into the aluminum frame, creating a leak-proof assembly that is designed for straightforward replacement of an existing flange-style hatch.

Outside handles let the hatch be opened from the deck when it is not locked, and integrated friction levers hold the lid open in virtually any position up to 95 degrees, so it stays put instead of slamming shut in a breeze. The hatch is finished in grey and is sized as Lewmar Size 70. It ships as a single hatch unit; mounting hardware is not included, so installers should have their own fasteners and sealant on hand. Lewmar backs this flange base hatch with a three-year warranty.
