Related Questions and Answers

Q: 1. can this be mounted to the ceiling?

A: From what I can tell, this is designed to be mounted to both the wall and ceiling. The hooks on are shaped to hold the rolls either from the wall or ceiling, not just the wall (as other answers would have you believe). The Varidrives that hold the rolls are also designed so that they can support something hanging from the wall or the ceiling. Like a previous answer said, you should mount into a wood beam when securing into the ceiling.

Q: 2. Does this work for C Stand? or only on autopole?

A: Only on an auto pole

Q: 3. How do I keep the roll at a set position, such as rolled up or partially rolled down? I don't see any way to keep it from rolling once it's in position.

A: When utilizing the Impact Varidrive with Silver Metal Chain, the roll can be at a set position based on how much tension is placed on the wheels on the back of the drive. Additionally, you can also add a counterweight to the roll such as the Savage Leader Bar. You may find the options for that product here. https://bhpho.to/3ChA3EZ

Q: 4. Do I need to buy a pole for each paper roll?

A: I agree with the previous three answers. You do not need to buy the poles, but I purchased them because there were reports that the cardboard tubes that hold the seamless paper start to bend in humid climates.

Q: 5. how many backdrop can i use this? and how many Varidrives are in the box?

A: The Impact Wall Mounting Kit with Metal Chain for Roll Paper holds three back drops. This kit contains the following: 3 x Impact Varidrive Set with Metal Chain (Silver), 2 x Varidrive Insert, 13' Metal Chain (Silver), Chain Weight Impact Background Triple Hooks (Set of 2), 8 x Concrete Anchor Bolts, and a Limited 1-Year Manufacturer Warranty.

Q: 6. What is the widest overall width in inches of a 107 inch paper roll with both end pieces attached?

A: I have these set up in my studio. The hardware sticks out approximately 6.5 inches on each side of the roll making the total width 120 inches.

Q: 7. Does this kit work with muslin sheets or anything other than paper?

A: No

Q: 8. Can I mount to concrete wall using 3 9ft and 7ft rolls?

A: You can mount to concrete. The Impact Wall Mounting Kit with Metal Chain for Roll Paper BH #IMVPDDSMCK only comes with two wall mount fixtures. All the rolls must be the same length.

Q: 9. I’m assuming the chain will only pull the backdrop down for 9ft rolls. But what if I have a 20ft roll, how do you pull the rest down and/or use the chain to wrap it back up when finished? Does the chain still work for that and at a certain point can you pull the rest down by hand without messing up the chain or how does that work?

A: The chain is a continuous loop with no stops, therefore the backdrop length does not matter.

Q: 10. is it compatible with (Manfrotto Manfrotto Background Baby Hooks) ??

A: Yes, the Manfrotto Background Baby Hooks work with Expan Drives and the Impact Varidrives.For safety I highly recommend using a heavy sand bag on each stand leg. When you unroll the paper background it pulls forward at the same time and you need the weight to help prevent it from falling over.
