The window handles are attached to the window frame by means of the 7 mm thick square pin. How deep the square pin must be pushed into the window to lock it depends on the thickness of the window. You can easily measure this in advance with the help of a thin object, for example a knitting needle. To do this, push the knitting needle into the opening as far as it will go and mark the spot with your fingernail. If you now measure this distance with a measuring tape, you will have the length of the pin.
In addition, our window handles are equipped with a sliding bearing for a durable, smooth and above all silent function. Without costly maintenance work!
