A doorstop is a small object used to keep a door open or prevent it from closing. It is usually made of rubber, metal, or wood and is placed on the floor behind the door to keep it in place. Doorstops are commonly used in homes, offices, and schools to allow for easier movement and ventilation. They can also be used to prevent a door from slamming shut in high winds or to prop open a heavy door.
