I have something like this. The bracket holds the weight no problem but the vinyl is to heavy for a cardboard seamless tube. (it starts to bend in the middle) so I replaced it with a plastic gutter pipe. The problem now is that it’s too heavy to wind up using the plastic chains, they either break or jump the teeth. So I have to wind it up by hand which takes a minute or so. So if I’m in the middle of a portrait shoot and the I want to clear the floor I tend to just loosely roll it along the floor. If you then leave it over night, the weight turns the loose folds into permanent creases!
