A spring-loaded door holder is a device designed to keep doors open without the need for manual support. It typically consists of a spring mechanism that allows the door to be held in an open position and automatically closes when released. This feature is useful in various settings, such as homes, offices, and public buildings, where hands-free access is often needed. These door holders are usually installed on the floor or wall and can be activated by pushing the door against them. They are commonly made from durable materials like metal or plastic, ensuring longevity and reliability in everyday use.
