Ladder Stand Support Bar

Seems like that could be made with some square tubing, a drill, a couple of brackets and some nuts/bolts.

Is the problem an existing bar broke? If so, I had one rust and break where the two telescoping ends overlap. I bought a 4' piece of 3/4" cadmium plated all-thread at Lowes. I used that because it is extremely stiff/strong and does not flex. I spanned it across the two ends, on the underside and fastened it with u-bolts and the flat plates that come with the u-bolts. The u-part of the bolt cradles the all-thread underneath, and the flat plate straddles across the flat of the square tubing on top. It may sound like a rig, but it is far stronger than the original telescoping tubing with a single bolt holding all of the pressure. Its about a $10-$15 trip to Lowes fix
