You see a handy trailer jack. It has a sturdy A-frame design and is rated for up to 5,000 pounds. The jack allows for height adjustment in the 14-inch range and retracts completely when towing. It is operated by a convenient handle that also serves as a grip when raising and lowering the hitch. The jack is safely protected from corrosion with a durable black powder coat finish. It is easy to install - it can be welded or bolted to the trailer frame.
