"Take grav-tube down 53B to level 4! Exit to cargo-tube ZZ8!"
―Instructions to Luke Skywalker[src]

A grav tube was a means of personnel conveyance between decks aboard starships. By manipulating a microgravity control, a user would adjust the gravity within the tube, enabling them to float up or down to reach another deck. The M-class Imperial Attack Transport used grav tubes.[1] Grav tubes were also used in multi-level cities on planets like Vorzyd V to travel between levels.[2]
