The Parts of the Door Knob

As complicated as a door knob appears it's a very simple device. The first part of note is the door knob. It does not have to be round and there is nothing very special about it other than the threads or square hole in the back. The spindle goes into this hole and connects to the other door knob. The spindle is simply a bar of sorts which connects the door knobs but has to be passed through the door knob latch. The latch mechanism is installed in the side of the door and the latch plate is then fastened. When the door knob turns it turns the spindle which catches the latch which pulls in the external latch allowing you to open the door.
