The BlackJack21 is a dolly jack positioning system
used to move locked vehicles away from curbs, or to assist in the alignment of disabled autos to rollback beds or conventional wreckers. They are also used extensively in the automotive body and repair industry. Their low profile enables them to be positioned under wheels even with flattened tires. Simply slide the Blackjack21 so that it cradles the tire and pump the foot pedal. The mechanical jack rack bar will push the rollers together, hence lifting the tire off the ground. One or two people can then push the vehicle in any direction with ease.
(A minimum of two BlackJack21?s must be used either installed on the front tires or the rear.) Our dolly jack comes with four heavy duty fully swiveling casters. You will be amazed at how little effort it takes to slide the vehicle on a flat surface.
Each Blackjack21 has a maximum capacity (working load limit) of 1,550 lbs., or 6,200 lbs. when used in a set of four (4). They will function with most wheels ranging from 13" through 16" in diameter and tires up to 13" wide.
