Rotary 7000lbs.-Capacity Rolling Jack for SM/SMO14, AR/ARO14, and RFP14 Four-Post Lifts. This rolling jack comes with pad adapters to lift the front, rear, or all wheels off of runways for brake, tire, alignment, and/or suspension work. The drop-in rubber adapters are made with high durometer rubber, and, when not in use, the jack rolls out of the way to provide unobstructed workspace between the runways. The jacks easy-glide wheels also roll smoothly in the track, while a sweeper pushes debris away from the wheel.
