One of the things we installed in our second studio space is a 3 Roller Wall Mounted Background Support. This not only speeds up production when we need to swap backgrounds, but we were able to push the background literally against the wall, and eliminated the use of heavy backdrop stands on the floor giving us a little more space to move. Our next project is to build a ceiling grid to hang our lights.
The ends lock inside of the seamless paper rolls with individual chain drives to raise and lower each backdrop. It was very easy to set up. Keep in mind that this requires a wall to mount, and all 3 rolls have to be about the same size to work. There's a seller currently offering this for much cheaper than what we acquired ours for, and it's available via Prime shipping too. If you've got a garage or place you often set up backgrounds at, something like this is about $50 dollars well spent. Find it (click here).
