A: The white section of the Impact Varidrive Drive expands to keep the paper from unrolling. To expand the Impact Varidrive Drive, you should be able to turn the black knob on the end of the device while the white section is inside the seamless paper's core to expand it until it is snug to prevent the paper from unrolling while in usage.

Q: 9. Does anyone have any input on this product? Will it work for 9 foot rolls?Thanks!

A: Yes, we use it for 9ft rolls in our studio (kept the paper on cardboard rolls). Very sturdy. Works great, cardboard tubes from the paper rolls start to warp over time (up for 8 months; could switch the paper over to a pvc pipe if warping gets worse). The only thing to look out for is paper doesn't stay rolled very well because there is nothing to keep it wound up. If you have high ceilings won't be an issue. It's a great system. for the price.
