Hi everyone, I'm revisiting this topic 1.5 years later because my repair only made it through two winters. I've decided rather than fixing the broken bottom channel, I want to replace it in its entirety. The bottom channel is like an upside down "h" and the wood sits in the channel. Then there is a piece of aluminum angle that is welded to the long part of the upside down "h". The hinge barrels (where the long hinge pin slides through) are welded to this angle. THE long part of the "h" has a curve to it, but I'm guessing this is only decorative. You can sort of see it in the picture below. Does anyone know where I can order this 'h' shape aluminum channel? I'm not opposed to building a completely new frame, so it doesn't have to be exactly the same, with the little curve, image, but it has to attach to the trailer using the long hinge rod (approx. 76", whish is the width of the trailer.
The entire frame of the ramp is made of the "h" shape, but only the bottom section has the angle welded to it for the hinge barrels.
I also included some of the dimensions in the picture.
Thanks!
