Don't Know - Quick Release Clamp (Rating: 3)

I have had two of these clamps for about 1 year. I bought them because I am a bit of a sucker for new tools. They sat in a drawer unused for a few months until I had a job that needed some tight clamping, the other quick grip clamps similar the Irwin XP did not have the gripping power.
I now often reach for these clamps first because they have excellent holding power for their size (18");
-they are easy to apply
-quick to release
-the tensioning lever is ratcheted
-you can adjust the tension easily from light to heavy grip.
-they are a reasonable price down under & I guess elsewhere if available.
