The Yost 32C 4.5" combination pipe and bench vise with 360-degree swivel base mounts to a workbench to provide heavy-duty clamping action, meets Federal Specification GGG-V-410B Type IV. The ductile iron body has a 360-degree swivel base that adjusts the direction of the jaws for proper placement. Hand-tightening the two lock knobs on the base secures its position. 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 four 0.65"-diameter holes for mounting hardware (not included).
