Two guide rods made of steel reduce wear and ensure a smooth, parallel operation. The jaws retract when pressure is applied, distributing it evenly across the entire workpiece. The adjustable clamping jaw is used in conjunction with the stoppers mounted at the top of the vise. There are mounting holes to accommodate wooden jaws of your choice to protect the workpiece. By pressing the trigger, a quick-release vise can be opened and closed without using the threaded spindle. Large and small workpieces can be swapped out quickly. The S.G. spheroidal graphite cast half nut ensures longevity and durability and can be replaced when worn.
