Hi-Lift Selection The Hi-Lift's predecessor was invented in 1905 and sold as the Automatic Combination Tool. The original jack was commonly known as the Handyman or Sheepherder's Jack, and years later it was renamed the Hi-Lift Jack. Our current product line includes the Slide-N-Lock Tie-Down System, an extruded aluminum rail and locking pin system for tying down cargo in pick-up trucks, the Post-Popper post puller and the Kant-Slam Hydraulic Gate and Door Closer. But the Hi-Lift Jack remains our best-selling, most popular item
