Thanks to the stabilising plastic insert in the cushion and a tapered side, the 2-in-1 pump wedge can be easily inserted into the narrow gap between the door and roof frame. The Winbag cushion professional is very stable and is inflated with the integrated hand pump (air bellows) after being inserted into the door gap. The amount of air in the pump wedge determines the gap between the door frame and the bodywork. A built-in shut-off valve holds the air in the cushion until it is specifically released from the vent valve integrated in the hose. The vulcanised grommet pocket makes it easy to operate the door opening mechanism with an opening handle without damage or scratching. The new 2-in-1 Winbag cushion thus makes vehicle opening much easier.
