French door knobs are a type of door knob that is commonly used on doors that open to the outside. The name “French door knob” comes from the fact that these types of door knobs were first used in France. French door knobs typically have a round, cylindrical shape and are made out of brass or other metals.
To use a French door knob, you will need to insert your key into the keyhole and turn it clockwise. This will cause the latch to retract, allowing you to open the door. Once you have opened the door, you can then push down on the top part of the knob to lock it in place. To close the door, simply push up on the knob and turn it counterclockwise until it locks back into place.
