On the face of it, these (and similar) inflatable small airbags are ideal for sticking underneath a door etc to get it to the right height for fixing the hinges. That's as may be and I've not used this bag for wooden doors.
But if you were thinking about using one of these to help fit a frameless glass door then think again.
The bag is made of plastic and so slippy. The bag is wedge shaped as it gets inflated. What do wedges have ? Slopes ! What is the coefficient of friction between slippy plastic and glass ? Negligible. You meanwhile are focussed on aligning the cutout in the glass with the hinges and keep pumping trying to get the door to the right height. But it doesn't seem to want to stay there. Because your very expensive frameless glass panel is sliding down the slope.
And before you know it, smashes against the floor. Well, not quite in my case as I realised what was happening and managed to grab it in time.
Just a heads up. And if anyone has found a way around this then I'd be interested to know. Certainly the wedge shape for anything thin is useless.
