Retracted height of just 2 and 9/16" for the smallest jack and 5 and 1/8" for the 20 ton, allows you to slip this jack into the narrowest of crevices. Jacks operate either horizontally or vertically. The perfect addition to any toolbox, this remarkable little jack has multiple uses that are limited only by your imagination. Use it as a jack or a spreader. Use it to turn your mechanical gear puller (puller capacity must match jack capacity) into a hydraulic puller. Use it vertically or horizontally in limited clearance situation.
