How does a striker work?

Together with a striker the hook bolt connects door and frame. The striker on image (1) is a safety reciever, which is part of the approved lock. But we also provide fully adjustable safety recievers (2).

For doors with wooden frames, there is a safety reciever with heavy-duty mounting plates in the frame. This kind of reciever is not suitable to retrofit, and if you thiniking of buying a new door with this option - contact a larger door manufacturers.
