High quality clamps

You can tell these clamps are made of high quality material, and Mastercraft stands behind their product with a lifetime warranty. I had an older set of clamps that needed replacing, and the quality doesn't even compare. It worked well when I used it to hold together the plywood on my diy bathroom project, and close my bags of grass seed and melting salt in the garage. The only disadvantage is how hard the clamps are to open, especially if you need it wider, it requires quite a bit of strength.
