I'm in the market for a good clamp that is ideally spring based, that is really strong. All I really need it for is to run a bar, mounts and mics from a mic stand hung from a ceiling. I can use some of the stuff that is mounted on the ceiling to take the strain off of the cables and clamp.
I have looked around and this seems to be the best I have found so far....
any places I should look in to for some other options?
