The wiper unit stroke length can be set to any distance from 45cm (17.7″) to 350cm (137.8″). The wiper blades range from 40cm (15.7″) to 100cm (39.4″) and the wiper arm length can be adjusted to fit the window on site.
For tall windows, an additional wiper can be installed below the window frame, increasing the wiped area by up to 100 percent. For wide windows, the wiper unit can be equipped with an extra arm and wiper blade.
A dual arm setup also allows for a longer combined stroke length compared to the standard unit, and can also be set to cover two adjacent windows.
