I cut these bars in half and use a half coupler with spigot (Global Truss 5034 Half Coupler w. half Con.) on each end to make 50cm bars that I can attach to truss or scaff to provide quick and easy hanging points.
Although you can buy similar things already made, this works out cheaper and gives a proper 48mm scaff bar to hang from, wherwas the others are a thinner bar.
