Yeah, I'm thinking of using something like that. Here is an image of the cross section I'm dealing with. I currently have the frame, glass and rubber gasket for the panels.
The fasteners and angle I have yet to completely figure out. I'm also thinking of adding some form of backing nut because threads will strip out that thin gauge aluminum like crazy. I'm thinking of something like this. I'll pop rivet them in place on the under side of the aluminum flange.
