After reading some reviews I took this tool with caution but was pleasantly surprised by the high quality of the whole tool. It is the quality I expect from a product made in the USA. Good metal construction, free from burrs and burrs, good welds, carvings, electroplating. Fits and clamps smoothly and securely. All clamps in this series have the feature that the nut that secures them to the work station is an "eye nut" (see drawings for other sizes). I prefer the regular M10 nut, which lifts easily, along with a heavy duty wing washer. But the craftsman did all the hard work and made a very handy clamp for a drill press or similar setup. This is the goalkeeper.
