You've got a bilge pump, a battery bank, or a wiring loom that needs a clean access point on the deck, and you don't want a square hole with a piece of plywood over it. This small access hatch is made from UV-resistant ABS plastic, so it won't chalk, crack, or fade in the sun. The lid is reinforced with a non-skid surface – no sliding when you're reaching for that fuse box at 7am. Weather-tight door gasket keeps spray and rain out. Mounts horizontal or vertical depending on where the access point sits. Cutout template included so you don't have to freehand the deck hole. Screw covers come with it for a clean finish. You'll need 10 No.12-14 countersunk screws to fix it down
