What does a door limiter do?

A door limiter is specifically designed to control the degree to which a door can open. By limiting how far a door can swing open, it helps in various scenarios such as preventing injuries or accidents, especially in areas with heavy foot traffic or where equipment might obstruct the full opening of the door. In the context of fire safety, a door limiter can also serve to contain smoke and fire within a specific area, enhancing safety by preventing the full opening of a door that could otherwise introduce more air (and thus oxygen) into a potentially dangerous environment. This controlled opening can be crucial during emergency situations where limiting airflow is important for managing fire behavior and maintaining safer environments for both firefighters and civilians.
