This newWall Mounting Kit for Paper Rollconsists of three Varidrive sets with cores, chains, and weights. It also contains two triple wall hooks on which you mount the drives. The three color-coded chains allow you to locate which of your three backgrounds is secured to which core. The three included weights hold the chains straight. Once installed, it will be easy to raise and lower your optional backdrops with a minimum of effort. The cores insert into each end of the backdrop and expand to stay firmly in place. The chains are able to be placed on either the left or right side of the wall hooks depending on your working preference.
