More detail is needed for this design, e.g. a plan view of hatch structure and details of the lifting handles. If this hatch structure is a frame & mid beam of C4x5.4 with a couple of angles for liftihg handles and 2x4's for Trex attachment, it will weight about 150 lbs plus the Trex. When it is lifted off, and set to the side, there will be a very good chance of damaging the adjacent Trex deck. I recommend we pursue a Bilco type hatch with Trex Deck inlay (e.g. Bilco type TER).

This hatch seems to resolve the hinge issues that we were concerned about in the previous Bilco hatch that we reviewed. See the attached for review.
