Patrol skylight tubing size.

[Rob]

The Patrol drawings show a piece of aluminum with a flange at the wing roots above the cabin area for skylight edges to attach. I see the kit built airplanes have a square tube bent to airfoil shape in these areas. Can someone tell me the size and thickness being used? 1/2” square? .035/ .049?
Thanks

1/2 in square is preferred. .035 wall.

Ok, thanks Virgil.
