Window handles

We offer as a standard the HOPPE Secustic windows handles containing 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. We offer also lockable handles (with a key or a button).
