Trimmed the .093 polycarbonate sheet to 43” long and 14” high after determining I needed 10”-12” above the deck lid. She used to be 5’-7” don’t know what now, no guts to ask. Bent the top of the polycarbonate sheet to provide stiffening and eliminate the need for a metal frame. Had to make a second bend due to problems. Bent each end with a 1” flange and then added a 2”wide additional polycarbonate stiffener to each side. Trying to not use metal exposed to view.
