Well....We have a roof top tent that is missing the awning supports. We could not match the awning to a specific vendor. As it turns out, these were actually about a foot short. I was able to locate some couplers the diameter of the rods. Since we only needed 2 rods for the awning, we used the couplers to join the other two rods. Through trial and trim, we were able to fabricate a reasonable replacement.
Thank You for the inspiration. Jim
