Automotive Authority LLC 4" Round Access Hatch Cover Deck Plate for RV Marine Boat

There's not a lot to it, but it does it's job. The part that opens seems to fit well and it all seems decently made. I used it for an RV water tank so it's easier to get in there and clean it out well. Does the job. Marked off one star because the sizing seemed slightly off my expectations (solved with a jigsaw) and because a gasket would have been nice (although that's easily solved with some butyl tape).

It serves it’s purpose. Measurements seem fairly accurate. It would have been nice to have included mounting hardware and a gasket to seal it into place. But it was a fair price for the quality & functionality.

Used these as an opening to pass 50 amp service through the floor of a cargo trailer. Don't want to put holes in the walls. Was exactly what I wanted for this purpose. They are quality made and the seal is great. Satisfied customer.

Solid well made deck plate sizing is accurate and seals well enough for kayak placement above the water line. I recommend silicon rRTV sealant for a gasket to ensure a water tight seal.

Used this while customizing a access hatch on my Perception sound kayak.Quality material and is completely watertite !

Worked for what I needed on my boat. Big enough to get my hand in to tighten some bolts which is exactly what I needed and looks good to.

Exact fit for the project. Installing inspection port on boat

Screws do come with this. Hatch seems durable.

As pictured, it has no rubber gasket so that will be an extra cost.
