"The Arcan A20018 Aluminum Floor Jack has a 3 ton lift capacity and a lifting range from 3-¾"" to 18"". It is made with aircraft-grade aluminum for lightweight maneuvering. And it is designed with dual pump pistons, a reinforced lift arm, a side-mount handle, and bypass and overload valves. Also, your vehicle is kept protected with the rubber saddle and foam handle bumper. We put all of our lifting equipment through a voluntary and rigorous safety certification process, as outlined by the ASME PASE-2014 Safety Standard for Portable Automotive Service Equipment."
