Heinrich 3SV Vise. Jaws open to 3". Features cam activated quick release design. Movable jaw slides easily to where you want it. When you move the activation arm the cam locks it in place and a little more movement applies pressure to the piece to be secured. Although this is a used vise new ones are still being produced in Racine Wisconsin. Weighs about 10 lbs. Cash only sale. I will not mail the vise but I will meet you at a mutually agreed upon location within Monroe Co., NY so you can inspect the vise thoroughly before deciding.
