[QUOTE="DaleH, post: 475080, member: 15636"] For full strength to the 'support ribs', if they could lie fully across the cut-out and sit on a 'lip' on each side, it would be stronger. Yeah, you'd lose a little of the opening, but 1/2" on each side shouldn't hurt you much. Clearly you'd need to design it to the thickness of your deck and then the hatch material itself. You'd cut a 'notch' in the L-angle or U-channel rib where it needed to sit somewhat flush onto the 'lip' of the hatch edge. See if you can visualize the concept from the sketch attached.
