Stop in for a cup of coffee

Morning Ex. The rail is basically u shaped with outward flanges on the top. I had a shop bend pieces with one flange in and one out. Welded them together to form the u shaped channel. They told me they couldn't do in one piece. Look up my thread Disturbed duster a few pics of what I did.

Gonna check your thread now, but do you mean like this? Or do the flanges on top bend out over the sides?
