The Triple Hook Set for Background Paper Drive from Kupo will support three optional Kupo or other compatible brand background paper drive sets. These hooks can be screwed or bolted to a wall or ceiling. This design will enable you to quickly and efficiently change your backdrop. You can also screw these hooks to the 1/4-20 tap on optional super clamps. In this way, the super clamps can then be secured to auto poles instead of bolting the hooks to your wall.
