A locker can be described as a compact, enclosed space, functioning as a cell for holding individuals. To hinder escape, it was equipped with a robust metallic door. Select models featured a narrow opening in the steel door, allowing the imprisoned individual a view of the outside. Typically, these lockers were quite diminutive, measuring only a few feet in width, thus precluding any possibility for a humanoid to sit down. Nym secured Vana Sage inside such a locker when he departed to engage in an assault on Trade Federation Superfreighters.
