Manufactured from close-grained grey cast iron for long, trouble free service. Accurately machined housings ensure smooth sliding movement and the solid steel guide rods reduce wear and tear giving the vices a smooth and true parallel action, free of side or cross deflection. Jaws have a "toe-in" feature so that, when fully closed, they meet only at the top, providing even clamping on the whole depth of the workpiece. Square body seating provides easy fitment under the bench top so that jaws are flush with the bench top. The steel main screw has buttress threads for smooth, accurate and responsive adjustment. Body and sliding jaw have provision for attaching wooden liners to protect the vice, workpiece and tools. 175mm in width and a maximum jaw opening capacity of 150mm.
