Adjusting the Hi Jack is as easy as 1, 2, 3 with a large, convenient adjustment handle, all you need to do is simply grab and adjust.

Set Screws and a Fall Guard

Sumner included some set screws in the design of the Hi Jack 781300 to support safety and transportation features on the stand. The first set screw is there as a double margin of safety for the user and the second set screw is there to lock the Hi Jack’s head to the stand in case you need it to for transportation, thus guaranteeing successful tool travel without the fear of losing pieces. Sumner has had the Hi Jack independently load tested for quality assurance as well as CE rated. Sumner’s High Jack is backed by over thirty years of jack stand manufacturing experience and finally, Sumner has engineered their very own patented fall guard  feature, which provides a 1″ safety around the lockwasher.
