I bought to use to hold up a hanging file at work. I bought clear so it wouldn’t show up on a painted wall. They support a (sometimes) full wall file, which could get somewhat heavy with books and metal equipment. The only drawback was the paper backing. I inadvertently peeled part of the foam off, while trying to get the paper strip off to place on wall. It still works, but it would have preferred the “tape” to come off easier.
