The background paper drive set consists of a pair of adapters designed to securely expand and lock inside the core of a seamless paper roll. One adapter features a plastic cog that accepts a plastic drive chain, allowing easy length adjustment for your background. It also includes a tension control feature, preventing the background from unrolling due to gravity. The set comes with a hanging chain weight to maintain tension. The background paper drive set easily mounts to specially made hooks, offering versatile and convenient mounting options.
