A force cage was a device that was designed for and used to contain prisoners, the first examples of which were seen some time prior to 3,956 BBY during the Jedi Civil War. Existing through to the era of the New Republic, these types of detention cells were, in essence, energy shields that took the form of a tube. The device itself consisted of a base and cap that was connected by a column at the back that also anchored it to a wall. This assemblage served as a conduit for the energy barrier, keeping it running and anchoring it in place. Force cages were found throughout the galaxy, on worlds ranging from the urbanized city-planet of Taris to the remote and desolate Sith world of Malachor V, and even aboard warships such as the Leviathan, the flagship of the Sith Empire's war fleet. During the years prior to the Galactic Civil War, a portable version of the still-popular device was developed; these types of cages were often employed by bounty hunters who wished to ensure the continued confinement of a live capture until delivery.
