This unique vise swivels a full 360º and then locks in place when the jaw is tightened. Vise can also be mounted sideways for versatility. Precision casting and machining make this vise a pleasure to use. Jaws measure 3-1/2" wide x 2-1/8" high and open to 4-3/4" capacity. Holes in jaws allow mounting of custom wooden faces. Great vise for Luthiers and anyone needing versatility.
