Wow I feel like a putz using mine for hanging some PZM's on 24" square 1/4 Plexiglass from the bottom of one of these and running a stereo Bar in the middle with Naks on top...
Eh It worked, was easy to adjust the angle of the PZM's...strong as a mofo too...somehow the PZM's got gone...I always wondered if I left them somewhere or they got pitched (I kept them wrapped in a towel at home)
All you clamping folks should love it...you could run three sets on the bar I'd bet
