Vertical lockers are ubiquitous and utilitarian storage units throughout the galaxy. The overall appearance and construction may change from one location to the next, depending on local norms and decor, but they are usually recognizable in function by any sentient. Because lockers make more efficient use of vertical space to increase storage density per cubic meter, they are preferred over trunks where available floor-space is more of a concern than portability.

The vertical locker is manufactured for public use and is now a common sight at spaceports, on board first response and emergency vessels, at recreational halls, as well as at popular vacation spots and schools throughout the galaxy. Freighter pilots also use them to maximize limited cargo space on board smaller vessels. Establishments with a large work force on rotational shifts, such as government military branches, find lockers especially useful in organizing their personnel. Additionally, they are used to comply with local health and safety ordinances where potentially dangerous materials and equipment are present.
