Here's a variation on the theme. We got the screen room sidewalls so we needed the support bars (hozizontal ones) to align with the edge of the awning
. Cutting it short will not work for the screen rooms.
I attached a 1x2 oak ledger in three places to the shell with 1/4 inch stainless bolts and acorn nuts. I put rubber washers between the board and the shell to seal up the holes. The ledger is a full 8 feet long I then attached the 2 four foot awning
rail to that. I liked this approach also because there are fewer holes in the fiberglass shell. The ledger made of oak is super strong and allows for very little flex. I also ripped a 45 degree angle on the bottom of the ledger so the ball and socket connectors could mount vertically.
Very please with the outcome. I recommend this solution for those using the screen room sidewalls.
