I'm look for the best way to attach a retractable awning to my aluminum sunroom. Through much thought and googling, the best idea Ive found is to mount a ledger board to the load bearing structural posts/studs, whatever you want to call them, and then attach the awning to the ledger. For reference the wall I'm attaching to is 16’ wide, and I looking at an awning about that width, that'll extend 19 feet out. Will my plan work, or do y'all have any better ideas?
