The Locker is an Epic Item Storage in Unturned 3. It looks as though it is a metal box with a classic vault handle on the front which makes it look similar to the Vault door.
The Locker is the most durable storage. It has the second most storage slots of all storages. Only the Metal Wardrobe is bigger. It can only be opened by its owner or group members, which makes it useful for players to store their items in without the risk of theft.
Like all other storages, if the Locker is destroyed, all items inside the Locker will drop on the ground.
