It's a C-Clamp, and one made to acceptable standards of quality. It's certainly nicer than many bargain bin ones I've seen, though nothing crazy either. Still, if it works well and is deserving of its price range, I feel no reason not to give it five stars.Everybody needs a C-Clamp or two. They are one of the most versatile tools anybody can have. You can use them to compress brake calipers, hold things while adhesive cures, stop a fan belt while you remove an engine cooling fan, and so much more. I bought 6-inch at this time because it's one of the most versatile sizes, but will likely return in the future for some larger ones.When this thing is clamped down it feels very solid and there's no play in the shaft. I'm happy with it. Worth noting that this is made in China unlike Taiwan where a lot of Tekton tools are made. That said, it's a hunk of iron. The finish on mine was near perfect.
