Car Door Wedge - The Air Fighter is the ideal car opening tool for police, firemen, and other emergency personnel, as well as repo people, wrecker drivers, auto repair shops and car dealers. When the unit is positioned between the car door and door frame and inflated, the door is pulled away from the frame just enough to allow an opening rod (included) to be inserted. The opening rod is then used to unlock the door from the inside of the vehicle (PR1, PR2, and NG-1 rods included).
