KF 520 combines innovative design with technical know-how. The window sash is not visible from outside due to its glass appearance and can optically not be distinguished from fixed glazing. This sash also contains the revolutionary locking I-tec Secure which renders levering of the window impossible - unrivalled in the branch. Integrated flaps press on all sides into the frame interior when locking and thus ensure maximum burglary protection.
