Keep critical compartments tidy, dry, and secure with this 13 x 24 locking marine access hatch in Polar White. It’s a sleek, OEM-style upgrade for tackle, batteries, rigging, and general storage where you want clean lines and dependable protection.

Engineered for the marine environment, the lid overlaps the frame and compresses against dual seals for a watertight fit. A corrosion-free integrated hinge provides a generous 160° opening so you can load bulky items without wrestling the door, and the locking latch helps prevent unauthorized access when you step away from the helm.

Install it on horizontal decks or vertical bulkheads—hidden fasteners keep the look smooth and professional. Sized for common retrofit needs with manufacturer-specified dimensions: outside 13" x 23-1/4", inside 9-1/2" x 19-5/8", and a cutout of 11" x 20-7/8" for straightforward, confidence-building installation.

Built in the USA with select globally sourced components, it supports American manufacturing while delivering the durability boaters count on—whether you’re chasing fish at first light, cruising with family, or buttoning up the boat at the dock.
