The Versi-Clamp wraps around the entire range of standard truss, from 2" OD down to 1" OD, all without marring the truss. The unique 2-position latch on the link saves time when switching from a 2" truss to a small truss; just connect to the second latch for the smaller sizes. The quick-release handle takes only 2 turns to be able to drop the locking mechanism and release the clamp from the truss.
