The unique inflatable jacks by PAFOWO make it easier to align and mount various structures. Their primary use is to create a gap between surfaces. This is helpful for opening jammed car doors, slightly lifting a wheel, etc. They can also be used at home – for furniture, windows, or metalwork. The kit includes three cushions of different sizes. They are made from high-strength materials resistant to damage, particularly punctures. Air is supplied through a bulb-shaped manual valve. Maximum load capacity is 300 pounds. The lifting range is from 0 to several inches.
