I modified marine hatch stops to use as seats for my aluminum props. Sourced from West Marine. They are chrome plated brass with rubber insets. I cut the rubber inserts down to 1/8" thick, then installed the stops on the hatch and counter.

I used 2 3'x 1/2" aluminum rods with rubber furniture caps as props. I angled the cut to match that of the hatch and filled the rod ends with epoxy.

I also installed the hatch light and paper towel holder.
