I set up a system consisting of Manfrotto's Autopoles, the 3-way holders and three paper backgrounds. I have set it up three times. The two times with all three backgrounds, the whole thing came down, fortunately with very minimal damage. The third I set it up with only one paper background hanging and no weight on the plastic chain. I did my best for the Autopoles to be straight and stick tight to the floor and ceiling but I cannot guarantee that the third much lighter set up will hold (the first came down after days, the second time only in hours). Any advice?
