I have an aluminum
extrusion shaped like this: see it as one piece, joined at the top (I can't make a simple drawing):
I am using it as a support for a traveller, spanning the cabintop and supported at the extremities with vertical blocks to keep the span horizontal on a curved cabintop. It is pitted after many years of attack by the elements and can't be made any prettier for anodizing. My only options are to hibuild epoxy
and LPU the extrusion, or find another similar one. The lower bases are about 1" wide, each, and the overall width is about 3 1/2", total length is 9 feet. It's about 1/8" thick. The traveller track bolts through it with a nut and washer on the underside of the upper horizontal portion. The total height is 1" above the base legs.
I have tried all my local (San Diego) suppliers and no one has a clue. I originally got it from a surplus metal place, but alas, no more can be found. Anyone have an idea where one could purchase
a short section of such extrusion?
