this is the best spring clamp money can buy. It's nice to see the vise grip folks doing so well. Just like they're timeless locking pliers these babies are headed for greatness. The entire product line from quick grip is awesome. The bar clamps and spreader clamps are a work of art. If you are considering purchasing any of the quick grip line clamps. Do it. It's money well spent.  Now get out there and clamp away.
