T-H Marine Sure-Seal Non-Locking Access Hatch – 13" x 23-1/4"

T-H Marine Sure-Seal™ Non-Locking Access Hatch – 13" x 23-1/4"

A large-format, watertight access hatch designed for horizontal or vertical storage compartments on boats. The lid-over-frame design uses two independent seals — one on the frame, one on the lid — to keep water out even in rough conditions. The corrosion-free integrated hinge opens a full 180°, giving 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 handles foot traffic and deck loads without flexing or cracking.

• 13" x 23-1/4" opening — large-format size suited to deep storage lockers, rod compartments, and equipment bays
• Dual-seal watertight design — independent seals on both frame and lid for superior water exclusion
• 180° corrosion-free integrated hinge — full lid opening for unobstructed access to deep compartments
• No exposed exterior fasteners — clean, finished appearance above deck
• Safety-texture surface — structural-grade material rated for foot traffic
• Non-locking — quick, tool-free access; no key or latch mechanism required

Parts Desk Insights

Best use case: Specify this hatch when a customer needs a large, watertight non-locking access point over a deep storage locker, rod compartment, or equipment bay on a center console or fishing boat. The dual-seal design makes it one of the more watertight options in this size class — worth calling out for compartments that see spray or standing water. The 180° hinge opening is a practical advantage on deep compartments where a restricted lid would obstruct reach. Note that this is a non-locking hatch — if the customer needs a lockable access point, a different model will be required. Always confirm the cutout dimensions before ordering; the 13" x 23-1/4" refers to the hatch opening, not the overall flange size.
