According to Stan Design, the Model J7000L Low Boy, a 7,000-pound capacity air bag scissor jack, offers the lowest cost of ownership of any jack. The jack provides a lowest collapsed height of only 7 inches and highest stroke of 10.25 inches (17.5 inches overall), with a compact design that is no larger than a hydraulic jack – but without the liabilities of broken pumps and costly repairs to hydraulics, the maker said. The J7000L also features a multi-level lock, adapter storage on the jack, a convenient pull handle,  heavy-duty control valve, powder-coat paint, and zinc-plated components. Stan Design adds the jack will fit virtually any lift, including Rotary, Challenger, Whip, Forward, JBC, Snap-On, Bend-Pak, ALM, Grand, Worth and more.
