Lewmar Medium Profile Flange Base Boat Hatch, Size 60, Anodized Aluminum Frame, Part 39960020

This Lewmar Medium Profile Flange Base Boat Hatch, Size 60 (part number 39960020) is a replacement deck hatch built around an anodized aluminum frame for corrosion resistance in the marine environment. The acrylic lid and seal fit into the aluminum frame to form a leak-proof assembly, making it a straightforward swap for a cracked or worn hatch lens without sending the unit out for repair. Outside handles let the hatch be opened from the deck when unlocked, and the handles include a locking function to secure the hatch when closed. Integrated friction levers hold the lid open in any position up to 95 degrees, so it stays put at whatever angle is needed for ventilation or access instead of slamming shut or drifting closed.

The hatch has a cutout dimension of 19-15/16 inches by 19-15/16 inches and overall outer dimensions of 22-3/4 inches by 22-3/4 inches by 1-1/4 inches high. It is finished in grey and weighs 18.9 pounds. Mounting hardware is not included, so installers should have appropriate fasteners on hand for the deck cutout. Lewmar backs this flange base hatch with a three-year warranty.
