The Powerbuilt Tools 4000 lbs U-Jack Garage Jack, No. 620516, features a patented design that allows the user to place a jack stand exactly on the same point as the jack lift saddle. The fork shaped lift saddle and open front end allows the jack stand to be placed in the cavity under the lift arm. Once secure, the jack can be lowered, leaving the vehicle resting safely on the jack stands at the exact lift point specified, according to the company.
