The components of this tool are made of a soft, ballistic nylon. Some air jack wedges are made of plastic and rubber. The ballistic style of air jack wedge will ensure that when used to separate the door from the door frame, it will not grab the stripping along the door, unlike the rubber or plastic air wedge.
On some vehicles, the door handle only needs to be pulled once to unlock the vehicle. And once this is done, the service technician should remove the air wedge and open the door.
