Frequently Asked Questions

Q: What sizes are available for the ABS round inspection hatch cover?

A: The hatch cover is available in three sizes: 4 inch, 6 inch, and 8 inch. Each size features the same screw-out mechanism, watertight O-ring seal, and non-slip surface, so you can choose the best fit for your kayak, yacht, or boat deck opening.

Q: Is the inspection hatch cover truly watertight?

A: Yes. Each hatch cover includes a rubber O-ring that forms a secure watertight seal when the cover is locked in place, preventing water from entering your storage compartments — even in rough marine conditions.

Q: Can I mount this hatch cover vertically as well as horizontally?

A: Absolutely. The non-skid surface and robust ABS construction make this hatch suitable for both horizontal deck mounting and vertical hull or sidewall mounting. The pre-drilled countersunk holes make positioning straightforward.

Q: Are screws included with the inspection hatch?

A: Screws are not included in the package. You will receive one hatch cover (cover plate and chassis). Standard marine-grade stainless steel screws are recommended for installation in saltwater environments.
