Part of the Varidrive system for easy raising and lowering of seamless paper, the Varidrive with Black Chain from Impact has adjustable inserts that tightly grip each side of the various sized seamless paper rolls. The Varidrive is then inserted into hooks like the Impact ME-122, ME-123 or the triple hook VPD-H3W. With the exception of ME-122 which fits in a Super Clamp, the other hook sets are bolted onto the wall.
You can load three rolls for example, onto the VPD-H3W. Each roll requires another Varidrive kit. You can purchase color-coded units to clearly identify which roll you're raising and lowering. The Varidrive can handle seamless rolls measuring up to 9' wide and weighing up to 22 lb. To strengthen large coreless rolls and prevent bowing, Cross Poles (VPC-5) are available from Impact.
