Kupo Background Paper Drive Set with Metal Chain (Gray)

The Kupo Background Paper Drive Set with Metal Chain (Gray) includes a pair of adapters that extend inside and through the middle of a seamless paper roll and lock for a secure hold. They expand to take paper cores from 1.8 to 3.1" in diameter, and one is raised or lowered via the twist of a knob as it drives down a length of metal chain. This chain stretches and compresses, tensing the paper roll and preventing it from quickly untwisting and careening downward toward your feet due to gravity off the roll. The Kupo Background Paper Drive Set with Metal Chain (Gray) gray 13' metal chain is stainless steel and, staying taut, won't stretch out of shape at maximum tension. It is kept tight under the weight of a chain weight that hangs from the bottom of the chain's loop, and now you'll have a smoother time rolling up as well as down.
