Here is a craftsman 5162 vise this is used, in fairly good shape but has rust and weighs about 54lbs and is a bench mount. The jaws are tight but need to be removed & cleaned up and you might need to replace the bolts. The part that it turns on is real good rod that tightens it is, but from someone using a hammer on it, it bolts in 3 spots on your bench. This would be a good addition to anyoneâ€™s shop or garage it is heavy and built very well by craftsman. The jaws are 4â€ wide and it opens up to 7â€ with out falling apart. We were told that this is called a 4 X 6. a 4â€ jaw and a 6â€ clamping area. It does have a few little spots that it turns hard we think thatâ€™s because it is dirty we believe that if it was completely cleaned up it would move freely and be as a new one, but this is one is used.
