The PowerLifter makes it easier to remove bonded windows - no matter which removal method you use! The bag is pushed between the window and the car body at a point that has already been cut through and inflated. By lifting the windshield, the remaining adhesive bead is put under tension so that it can now be cut through much more easily. The bag made of fiber-reinforced fabric is extremely hard-wearing and has an incredible load-bearing capacity: the valve of the rubber ball only opens at around 150 kg.
