The Impact VPD-DSMC2 Varidrive Set makes it easy to raise and lower seamless background paper rolls. The set includes expandable Varidrive cores that grip the paper roll's inner tube and allow you to change your backgrounds with a simple pull of the chain. For ease of operating multiple backgrounds, Varidrive sets come with a selection of red, gray, black, and silver chains to quickly identify the appropriate background. Built with features like a large-tooth gear wheel and flat metal chain, the Varidrive set is easy to install and can be used with paper rolls up to 12 feet wide and weighing up to 42 pounds. The Varidrive set can be suspended from a variety of accessory hooks. Use Impact VariPoles and Triple Background Hooks with Super Clamps to suspend backgrounds in areas with extremely tall ceilings. You can also use the Varidrive set with Impact's Cross Pole to expand compatibility with uncored paper rolls and fabric backgrounds.
