Solid metal vice enables exact and strong clamping on the workbench. The grey cast iron jaws run on two 25 mm strong steel guide rods virtually free of play. The 24 mm strong, precisely milled spindle has asymmetrically shaped threads to withstand extreme loads. The extendable dog enables clamping of longer objects. Easy installation by screwing the vice to the bottom of the bench plate. Jaw drill holes for fastening wooden blocks.
