To deploy a Tool Cupboard drag it onto your Action Bar, select it and click(default "Left Mouse Button"), while aiming at the desired location. Initially you will be affected by a "Building Blocked" debuff as a newly spawned cupboard's Authorization List is empty by default. To gain "Building Privilege" and be able to build in the area, target the cupboard press the Use key (default "E") to authorize yourself. Pressing the Use key, while already authorized, will remove you from the Authorization List. It is possible for multiple players to approach the cupboard and authorize themselves at any given time. Should you need to restrict authorized players' building privileges, you can clear the Authorization List by targeting the cupboard, holding the Use key in order to bring up the Wheel Context Menu and selecting the "Clear Authorized List" option. Any player, regardless of his authorization status, may clear the List. A Tool Cupboard can be locked by a Code Lock or a Key Lock. The Tool Cupboard has 24 slots for building upkeep. Resources can be stored inside and have a cost base on the size and composition of a base. If these resources aren't deposited the base will begin to decay.
[Outdated information. Tool Cupboards no longer work this way. You may only have one Tool Cupboard per base.] Recognizing and being aware of the Tool Cupboard's features and limitations is imperative for establishing a secure, well-protected base.
The "Master Tool Cupboard" needs to be protected at all costs. If raiders were to gain access to it, they would be able to build and deploy items(stair case, etc.) inside your base, even if they were inside the protection area of any secondary cupboards, on which they aren't authorised. This is due to the fact that the "Master Tool Cupboard" overrides the effect of any secondary ones.
Aside from deploying your primary cupboard in hard to reach places or behind heavily fortified walls, if you have external cupboards covering your base, you could try to position your primary one in such a way that it would get destroyed during Rocket raids. If you place it snuggly in the corner of your foundation/floor before building walls, a Rocket fired at that wall will likely demolish the cupboard with its splash damage. Once destroyed, the external cupboards will apply their building restrictions.
The "Master Tool Cupboard" room may also be booby-trapped with Landmines. If a single one is detonated, a chain reaction will be triggered, causing any adjacent ones to detonate as well. It takes 2 Landmines to demolish a Tool Cupboard.
An important tactic to deter against bottom-up raiding is to use the cupboard's downward extending, hemispherical protection mesh to your advantage. Starting from the topmost floor of your base, additional cupboards may be placed on every other floor below, since a cupboard's protection mesh only extends half a floor downwards. For example, a player could deploy his primary cupboard on the 5th floor, then a secondary cupboard on the 3rd and finally another secondary on the 1st(ground/foundation) floor. That way, if raiders were to gain access to the bottom cupboard, they would be able to only build up to the second floor, at which point they would be restricted by the cupboard on the 3rd floor. It is vital that you always place a cupboard on the ground(foundation) floor as to prevent griefing. If you want to employ this tactic, a good rule of thumb is to place your primary cupboard on an odd floor and work your way downwards, placing additional cupboards on every odd floor as well.

- It takes 60 seconds to craft one Tool Cupboard.
- The Tool Cupboard has 100 health.
- The Tool Cupboard's protection applies to not just Building Plan structures, but deployable items such as Sleeping Bags, Chests, Lanterns, etc.
- It is advised when building a base that you start off by placing your Tool Cupboard and securing it. Otherwise, players may come and deploy their own cupboards, lock them up and restrict building access to your own base, effectively claiming it for themselves.
- The Tool Cupboard has a note on it that reads, "Rust Beta Release Date =" and then the Lambda symbol with a subscript 3 beside it. This is referencing the Half Life 3 release date which has yet to be announced.
- Wooden Ladders were prevented by the Tool Cupboard with Devblog 75; this was reversed with Devblog 158, the update that also allowed the twig tier.
