Put your heavy shop workbench, stand, and open-base saw on wheels with the touch of a toe with the DCT Heavy-Duty Retractable Contractor Saw Swivel Caster Wheels Assembly Set with Mounting Plate Bracket 4-Pack. They are 360-degree freely pivoting casters with a simple, innovative, and secure foot pedal mechanism to elevate your workbench and move up to 600 pounds. When in the upward position, your workbench is not resting on the wheels, so you have a safe and stable work environment. If you wish to move your heavy bench, push the foot lever down and the bench is moveable. We have you covered so you can focus on achieving your woodworking and craftsman goals with ease and confidence. This package includes 4 caster wheels attached to lift brackets, hardware, and mounting instructions.
