The T-H Marine Sure-Seal™ HAT13241DP is a 13" x 23-1/4" non-locking access hatch designed for horizontal or vertical storage compartments on boats. The watertight lid overlaps the frame and uses two independent seals — one on the frame and one on the lid — to keep water out even in rough conditions. The corrosion-free integrated hinge opens a full 180°, giving you unrestricted access to the compartment below, and there are no exposed fasteners on the exterior for a clean, finished appearance.
Built from structural-grade material with a safety-texture surface, this hatch is designed to handle foot traffic and deck loads without flexing or cracking. Installation is straightforward with a standard cutout and concealed fastening.
- 13" x 23-1/4" opening — suits large storage compartments
- Watertight lid-over-frame design with two independent seals
- Corrosion-free integrated hinge — opens 180°
- No visible exterior fasteners for a clean finish
- Structural material with safety-texture surface
- Non-locking — quick, tool-free access
Best Use Case: Ideal for large under-deck storage compartments, rod lockers, or live well access on fishing boats and centre consoles where a watertight, non-locking hatch is needed. The 180° hinge opening makes it practical for deep compartments where you need full access without the lid obstructing your reach.
Parts Desk Insights: This is a non-locking hatch — if security or locking access is required, a different model will be needed. The dual-seal design makes it one of the more watertight options in this size range, which is worth noting for compartments that may see spray or standing water. Confirm your cutout dimensions before ordering; the 13" x 23-1/4" refers to the hatch opening, not the overall flange size.
