Shown here is a Winbag inflatable air shim.
More specifically, it’s a durable inflatable air wedge that’s made from a fiber-reinforced non-marking material.
It’s as flat as 3/32″, allowing it to slide into narrow spaces, and can be inflated to up to 2″. It can lift up to 300 pounds, per Winbag.
The Winbag air shim is said to be useful for installing doors, windows, cabinets, appliances, and all kinds of other fixtures where you might need to make careful height or spacing adjustments.
Have you used one? What kinds of things have you used it for? Don’t have one? What kinds of applications might you use this for?
Price: ~$15-20 each, depending on store and quantity
I’ve heard lots of good things about the Winbag, and can see a few things I’d use it for (such as installing anti-vibrational pads to a washing machine that’s already installed and blocked in place).
This demo video, although a little infomercial-toned, shows what the Winbag can do:
There’s a competing brand, the Air Shim by Calculated Industries, which can sometimes be found for less money.
They also offer a larger version, the XL 500.
