I work with some wonderful staff and one in particular is a great carpenter/activity designer. He attached the suspended dowel from the ceiling so that the individuals (with developmental disabilities) can hang them up. The hangers are on the floor so this gentleman has to repeatedly move up and down to pick them up- receiving wonderful vestibular stimulation. He enjoys sorting them by color- he chose to do that without being told and it appears to be quite relaxing for him.
The cord holding up the bar is attached to small carabineers and these are attached to small hooks attached to the ceiling. It is not designed to be pulled with force or hold much weight but it seems to be working really well for this activity.
