This is a complete Interfit COR762 Portaprop Background Support System. It is a background support system that will allow raising and lowering up to 3 cored backgrounds without climbing a ladder (This set comes with 2 drives). The Portaprop poles are held in place between a floor and ceiling as high as 10'10' with a powerful spring lock. Up to three Drive Sets can work with their plastic color coded drive chains. The Drives are held by the background hook set, which is clamped to the Portaprop poles. If your backgrounds do not have cardboard cores, simply add the Alu-Core crossbars, available separately.
Color-coded chain drives make backgrounds easy to identify
Extension poles are available for ceilings higher than 10' 10"
Bases are available for working in areas with very high, or drop-ceilings
