A door stop is a simple device used to hold a door open or closed. It prevents the door from swinging too far or closing unexpectedly, which can be useful in various settings like homes, offices, or schools. Door stops come in various shapes and materials, including rubber, wood, and metal, allowing users to choose one that fits their needs and decor. There are two main types of door stops: stationary and portable. A stationary door stop is often mounted to the floor or wall, while a portable door stop can be easily moved and placed wherever needed. Both types help protect walls and furniture from damage caused by doors slamming or swinging.
