Outlet Lee Valley Winbag Air Wedge

This tool was designed as an adjustable shim for window and door installation, but its ability to expand from flat (1/16″ thick) to 2 3/4″ and support up to 300 lb (135 kg) gives it utility beyond its intended purpose.

It can be used as an inflatable crowbar to pry objects apart or lift furniture or appliances high enough to insert a solid shim.

Pumping the rubber bulb takes little effort, so one person (and one or two bags) can lift heavy objects, and by adding or releasing air as needed spacing can be adjusted precisely.

Constructed of heavy-duty fiber-reinforced rubber with triple-welded seams, the bag measures 6 1/4″ × 5 7/8″. Made in Denmark.
