Title: Don't Buy...
Review: I have owned 30 or so of these clamps. 2 to 3 years ago they worked just fine on an 1 1/2" pipe. I think they switched Chinese manufactrers and the new are crap. Once they are tightened down all the way around the pipe, they are still loose and swing freely around the pipe. I can't have this. If you are a DJ, get these clamps from Odessey(like the DJ cases). They make great ones! Good luck.
