Cheap and got the job done.
Just what I needed. Plenty strong to roll out waterproof taping on a utility trailer roof. It is cheap and I can’t find anything to complain about. Maybe if you want to be gorilla Joe , it might not hold up to putting your body weight into the rolling process. But what needs that much force….
