The bar lock FOS550 is a high security lock for windows and French doors with two stable security points, top and bottom.
The patented locking system gives the window lock an extremely high resistance to pressure loads and lever attacks from the outside.
Due to the particularly narrow design, the FOS550 window lock can be used very universally, i.e. on almost all inward-opening windows and French doors, including most double-wing windows with and without a central bar. The appearance of the lock convinces with a modern design with elegant lines and slim, shapely bolt bars.
