A doorstop is a simple device used to hold a door open or closed. It can be made from various materials, including rubber, wood, or metal, and comes in different shapes and sizes. Doorstops are commonly found in homes, offices, and public buildings, providing convenience by preventing doors from swinging shut or slamming against walls. There are two main types of doorstops: wedge and spring. A wedge doorstop is a triangular piece that can be placed under the door, while a spring doorstop is often mounted on the wall or floor and uses a spring mechanism to hold the door in place. Both types help improve safety and accessibility in spaces where doors are frequently used.
