Amarine Made7 inch Boat Round Non Slip Inspection Hatch Detachable Cover and Pre-drilled Holes in Deck Plate Easily to Install Cut Out Dia:7-1/2" Outside Dia: 9-4/5"

Nice quality opening inspection port for a very reasonable price. I needed two of these to access a closed floatation compartment on a dinghy to install some launching wheels. I won't be needing to open close these on a frequent basis and the lack of screws/ mounting bolts are not a problem since i have that stuff lying around and its probable better quality stuff than what would have been included.i might also get a few more to use for my Laser sailboat to do the typical mast step repair.

Great little thing. Only improvement would be a quarter turn? design where you don't have to spin it so much to get it off. As mentioned it doesn't come with screws though I just slapped water proof caulk around the rim and didn't use screws anyway.As one guy mentioned leave the top screwed on when installing so you don't bend the frame to get it in place and make it so it won't screw on.

not much to it. it's a solid 10 inch twist hatch

Decent study hall covers the stick up a little too far for my liking

Well made, easy to install, easy to open/close, glad we bought it. The only surprise was there was no cutting template printed on the box. Maybe they can add that to the back side of the printing on the packaging.

They are well made and fit on my boat with minor cutting to replace older existing covers but once installed they are great. Good value

Bought this as a waterproof hatch for a build that I'm doing. Unfortunately it did not come with the rubber gasket that was specified in the pictures, but I made do with a waterproof sealant around the edges.

Its good for update the boat and his gadgets
