Rust airlock: how to use two doors

A Rust airlock uses successive doors to control the route into a base. Plan their swing so opening an outer entrance does not casually expose the inner route.

Check it before relying on it

1. Stand inside and operate each door separately.
2. Check where the open door leaves space to move.
3. Walk through in both directions and close the route behind you.
4. Repeat after moving nearby objects or changing the entrance.

The developer's building glossary distinguishes airlocks from added wall layers. It also describes a configuration that forces a door to close before you can fit through. This page explains the function; it does not reproduce any source image or promise that every pair of doors has that behavior.

Hizzle recommends practicing the opening sequence before carrying a valuable load. A second door is useful only if you understand how your own entrance operates. Exact current explosive costs, door durability and raid scenarios remain outside this first layout explanation.
