Door Closer
The RUST Door Closer is a single-purpose tool located under the construction tab in the F1 Console, only available in the game through manual spawning. They are not a default item available in the game.
Door closers, in name, really remove all mystery to their purpose; closing doors. When attached to any door type in RUST, they will close that door when left open after a predetermined amount of time. They can be removed with a hammer and recycled for a small number of metal fragments, and the chance to get a Metal Spring.
