I assembled and installed the awning. I would follow the suggestion to have a two-person team. I used a support (cross) beam to which we attached it because the exterior materials on my house were not conducive to aq flush mount. I must say that the awning held during the 3 seasons but the panels were blown out, literally due to gale force winds. I cannot fault the product. The recent weather has decimated my roof as well as many neighboring friends'. The winters are wicked up here!! NOW, the frame didn't move a lick. It is so sturdy. I'm going to figure a more secure way for the panels to be held in place and I know that the awning will serve us well.
