Calculated Industries recently announced its new “pry bar” and leveling tool, the AirShim - a llittle hand-pump inflatable bag that can can be used to lift windows, cabinets, sliders, and more during installation.
It joins the WinBag, a similar product introduced earlier. Steve Demetrick used this tool on a recent project described in JLC (see "Installing High-Performance Windows," Oct/15). The difference, apparently, is the the AirShim can lift 300 lbs; the WinBag 220 lbs.
Tools of the Trade senior editor, Chris Ermides, looks more carefuly at the AirShim.
