Secustik® – The window handle with the built-in security you can hear
Our Secustik® window handles contain a patented jamming-device which provides integrated security. This makes it more difficult to move the window fitting unlawfully from outside. It works by a coupling element acting as a sort of mechanical diode. This allows for normal use of the window handle from inside, but jams the handle if anyone tries to turn it from outside by way of the fitting.
As the handle is turned through 180 degrees from the closed position to the tilt position, the jamming-device makes a series of clicks – proof of the built-in security you can hear
