The pump wedge is a high-quality inflatable wedge which is made of heavy duty non-marring vinyl material. This air wedge slides between the vehicle door and the weather stripping on the door frame, then the pump is squeezed, which then inflates the air pump wedge and separates the vehicle door from the frame. This provides enough room to insert a car opening tool. This wedge does not leak and can bear the pressure of 200 kilograms.

Do not over inflate, be sure to release air after each use.
