The 30-Ton Bottle Jack, No. BT30, from OTC offers a maximum height of 17-5/8". Compact and constructed with a forged base and cylinder, this jack is built to last. The chromed pump piston and ram increase rust resistance and help to extend the service life of the jack. The inline design makes it easy to use for both positioning and lifting. Additionally, the built-in extension screw on the ram provides added height. The BT30 meets or exceeds ASME PASE-2019 safety standards for portable automotive service equipment and includes a built-in safety valve that prevents overloading.
