The Background Paper Drive Set is a pair of adapters that expand and lock securely inside the core of a roll of seamless paper. One adapter has a plastic cog that accepts a plastic drive chain so that you can adjust the length of your background comfortably and a tension control so the background doesn't unroll by itself due to gravity.
The 3/8" Finger Nuts are used to securely lock the 9.Solutions 3/8" rods to different accessories. The 3/8" Connecting Nut is used to connect multiple 9.Solutions 3/8" rods together, allowing you to make longer rods.
Multiple rods can be used to create larger structures for rigging small cameras, lights, and a variety of other equipment.
