<div>I had both my hatch and tower machined flat before installation. Even with that there still seems to be a tiny gap. I fiddled around with the hinge mounting for ages, trying to eliminate the gap, but found like Alec says, with the dogs tightened, it dissapears. It doesnt leak.</div>

<div dir="ltr">OK, I wasn't really sure. I know this hatch/tower ring has historically functioned. This hatch is pretty beefy in my opinion. I have bigger fish to fry so I will move on for now. I had the hatch on as I am evaluating how I can make it open from the exterior. I would like to do this by only having to create 2 penetrations. <br>
