Title: Too Large
Review: Either I got a 7" clamp sent to me in error instead of 6" or this thing is too big and won't tighten enough. I used it on standard 6" flex ducting and even at the max tightness it just lays limply on the connection rather than tightening.It's also fiddly to put together and keeps coming apart as you try to tighten it if you're not careful.
