The Yost Vises 133C 5" combination pipe and bench vise with stationary base mounts to a workbench to provide heavy-duty clamping action, meets Federal Specification GGG-V-410B Type IV, and is made in USA. The ductile iron body has a flat, stationary base for secure mounting. The top jaws and pipe jaws are made of hardened steel, are grooved for enhanced grip, and can be replaced when worn. The pipe jaws are set back to prevent interference with the use of the top jaws and can be adjusted both horizontally and vertically, customizing the grip for each pipe to prevent marring, crushing, and bending. The jaws draw closer together or farther apart by turning the vise handle clockwise or counterclockwise.
The main screw that controls the jaws has been continuous rolled for high strength and is covered by a bar to protect it from damage. A rubber washer on either side of the handle prevents unwanted sliding when turning, and the balls on each end unscrew to enable replacement of the handle if worn. The base has two 33/64"-diameter holes for mounting hardware (not included).

Vises use the clamping action of jaws to hold a workpiece in place for applications such as drilling and sawing. Vise styles are categorized by how the device is mounted. For example, bench vises mount to a benchtop; drill press vises bolt to a drill press; and woodworking vises fit underneath, on top, or to the side of a workbench. A vise's jaw opening and throat depth should be large enough for the workpiece.
Yost Vises manufactures a wide range of vises, including bench-mount, woodworking, and drill-press styles. The company, founded in 1908, is headquartered in Holland, MI.
