I'm making a 4x6 gate for a trailer that is 6x8 in size. I'm looking for ideas on how to mount it to the back of the trailer. Maybe something other than welding a number of little barrels to slide a round stock through. My idea is to get some round stock and slide it through some type of tube material and bend the ends of the stock to go into a bracket welded onto the trailer. The gate will be lower to the ground to remove mowers. Any ideas ? This gate will welded to the tube material.
