I exteneded my dura truss to the last hole, and used the locking pin and the side brake to keep it there. After the concert it wouldn't come down. It was like the inner pole was hitting a seam/joint inside the outer pole. We had to have someone stand on a case and lift the end of the truss on the jammed side by hand, remove the jammed stand, lower the side that would work to the lowest position, extend the jammed side until it just about fell out to realign it, finally got it to come down, then rebraced the truss.
Anyone else have this type of stand jam?
