I sometimes use a telescopic squeege handle as a cross bar :shrug: it goes from 4ft to 12ft just took the squeege part off, two clamps from an old drum kit & thats it. I suppose you could drill each end & put some kind of pin/bolt through & into the top of the stands if your stands have a whole in the end.

Try a couple of Manfrotto superclamps.
Cheers, found the Super Clamps, and cheaper than eBay - just need to find the telescopic 3m background roll holder to go with them now... can't find that on the Karlu site....
What about one of these?
Btw, I haven't forgotten about your snoots, I'll try and get over and get them in the next few days![]()
