"The Yost heavy-duty ductile iron woodworker's vises are unequaled in quality. The 7-WW has stood the test of time since Yost's establishment in 1908. Solid steel dogs in the front jaws, when used in conjunction with a bench stop, allows oversize work to be held securely on the bench top. Machined, toed-in jaws provide a solid grip, while steel no-pinch handles provide adequate clamping pressure. The front and back jaws are drilled and tapped or countersunk holes to allow for optional wood facing. Vises easily fit any bench up to 3in. thick.
