The Multi-Purpose Vise uses a "lift on/lift off" BenchMate mounting system. Unlike other bench vises, the Multi-Purpose Vise adjusts to any angle because it tilts and rotates on two axes. Workpieces adjust with the user, adding comfort and efficiency to the bench setup. It is precision made from steel for rugged dependability. Includes vise assembly and wrench. Jaws open to 1.8" and are 2.3" wide by 1.6" tall. Fits any BenchMate Fixed Mounting Plate and Optional Mounting Adapter (not included).
