Like HPC’s Original Air Wedge, the Universal Air Wedge is made of a sturdy vinyl and equipped with a bulb pump and release valve for quick and easy inflating and deflating. It slides in between the vehicle door and doorframe. Then, when inflated offers ample room for the insertion of a car opening tool so that the vehicle can be opened safely and quickly from the inside. The longer width gives you a larger gripping area for inserting the wedge into the top corner of tighter fitting doors.
