The RIDGID XF45 and XF50 combines the strength and durability of forged steel, with the time and effort savings of a Quick Action Trigger. These vises are the only forged steel bench vises on the market with this Quick Action. Traditional bench vises rely solely on hand cranks to tighten and loosen the jaws. By just flipping the Quick Action Trigger, the jaws can easily slide into the desired position. This trigger significantly reduces the amount of time and effort when working with this vise.
