The Carlyle Tools 2-Ton Hybrid Floor Jack, No. 791-6450, is a professional grade jack featuring bent aluminum flange side plates giving this jack increased strength by reducing the torsion applied. The load-limiting bypass valves prevent use beyond capacity and over extension of ram. Its power unit includes long lasting, high performance seals and hydraulic fluid. Double pump pistons for fast saddle rise to load and the rear mounted handle allows for maneuverability.
