4 inch duct hose hanger

I vent my laser fumes outdoors via a 4 inch plastic ducting. I would often trip over it or somehow manage to put pinholes in it from it laying on the ground thus came up with an easy solution to hang it instead of it laying on the ground. It fits a 4 inch hose pretty loosely. Since the hose is pretty light weight, I use 3M command strips to glue it to the wall but one can glue or use other adhesives to secure it to the wall. This design unfortunately was not meant to use screws and it would be hard to alter to allow the use of screws thus should probably be used with adhesive.
