Placing a hanger on the doorknob can work as an effective reinforcement to lock the door from the inside and prevent intruders from entering.
- Necessary material: A sturdy metal or plastic hanger.
- Procedure:
- Adjust the hanger to fit the doorknob.
- Before closing the door, hook the hanger onto the knob and the locking system.
- If someone tries to open the door from the outside, the hanger will act as an additional lock, making it difficult or impossible to open.
This method is especially useful in hotels or rental locations where safety may be a concern.
