The entirely novel ALU XT hardware with its innovative operating rod technology is setting new standards in production. Irrespective of the window dimension it gets on with a maximum of five operating rods and makes it possible to easily insert additional locking points or accessories without machining the operating rod any further. The ALU XT is designed for fast production and stands for optimised production processes and a revolutionary easy installation with flexible assembly sequence as well as self-positioning components which reliably compensate for tolerances.
