Profile knob cylinder
The knob cylinder is designed in such a way that it has a knob on one side and a key insert on the other. This allows the door to be locked and unlocked from the inside without a key. The door can still be opened from the outside with the appropriate key. Our range includes SX profile knob cylinders in various lengths and the SX toilet knob cylinder, which is suitable for the toilet area.
