Installation animations for a half round duct suspended below a ceiling, this system has special cross bars so that (1) you can hang the duct from them and (2) they keep the half round rails at the correct distance apart - if we didn't have these the duct would try to become round shaped when it inflates and the rails would pull together. In this animation we show the rails being hung with wire droppers, this can also be done using M6 threaded bar (6mm).
