YaeMarine Marine Deck Access Hatch, Black, 17-1/4" x 12-3/8", Low-Profile ABS with Weatherproof Seal

YaeMarine's 17.3" x 12.4" marine deck access hatch is a heavy-duty, low-profile ABS hatch with a 180° hinge, weatherproof rubber seal, and pre-drilled mounting for quick boat installation.

This black access hatch is built for marine environments where corrosion resistance, UV stability and a flush appearance matter. Constructed from non-corrosive UV-stabilized ABS plastic, the hatch resists harsh sun, salt spray and routine wear while giving a neat, finished look on flat decks, consoles or vertical panels. Multiple size measurements and an easy-install design make it a practical choice for small to medium compartments, storage lockers, or system access points aboard recreational and working vessels.

How does this hatch stand up to marine conditions?

The YaeMarine hatch uses UV-stabilized ABS plastic that resists fading and degradation from sunlight and salt exposure. Its non-corrosive construction prevents rusting or pitting that metal alternatives often experience. A rubber compression seal helps keep out unwanted moisture when closed, improving protection for gear and systems stored behind the lid.

• UV-stabilized ABS resists sun damage and discoloration
• Non-corrosive construction suitable for saltwater environments
• Rubber seal provides weatherproofing on vertical and horizontal mounts
• Pre-drilled, countersunk holes reduce installation steps

The clear opening inside the lid is roughly 14" x 9.5" (358 x 240 mm), providing adequate access for wiring, storage or moving small equipment through the hatch.
