FotodioxTriple-Roller Roll Paper Drive Set With Wall Mount Support For Mounting 3X Paper Background Roll

Are these strong enough to support 9 feet rolls of paper? I just bought 9 ft x 50 ft rolls of backdrop paper. Thanks

Would this work with a roll of craft paper? What's the diameter of the pieces that fit into the tube? What is the weight limit?

Can I hang up the paper on just these rolls (10 ft savage seamless), or are there any specific poles recommended that go on top of the rollers?

Can the width be adjusted? My room is 106 inches wide
