The Winbag is a heavy-duty vinyl air bag with a short hose, a valve and an inflator bulb. The bulb builds pressure, and that pressure is released with a push-button valve. Clients who are installing kitchen cabinets, for example, can put a Winbag under the cabinet, pump it up to level the box, then adjust leg levelers or add shims as necessary. The same principle applies for almost anything that needs to be shifted into position for level or plumb, such as windows, appliances, workbenches, whatever.
 
The Winbag should be used any place needing controlled moving pressure, and is a substitute for pry bars, wedgers, etc. Manufactured in Denmark, the Winbag is rated to lift up to 220 pounds.
