Prevent upending semi-trailers during loading and unloading operations with the Global Industrial; Quick-Adjust Stabilizing Trailer Jack Stand. Easy to set in place, the wheels simply roll under the nose of the trailer and unlocks the restraint. Angled handles allow the unit to easily be tilted and repositioned like a hand truck for easy operator use. Its bright yellow powder coat finish provides high-visibility and promotes safety. Ideal for use in docking stations, warehouses, and lots, this jack stand is made of durable steel construction and solid 16 rubber transport wheels for strong impact-resistance.
