The Porter-Ferguson Line of Jacks offer several choices of powerful and rugged remote-control manual or pneumatic-powered hydraulic models. Each jack comprises either a hand or air-powered hydraulic pump, a hydraulic hose, a quick connect coupler and a ram. The five pump options range from 7,000 psi to 10,000 psi and all can be used with a variety of ram sizes and types. All pumps feature a steel, drop-forged broad base, ensuring stability even in awkward positions and able to withstand years of hard use. These jacks are made in the U.S.A.
