What is the "return" on an L-shaped desk?

The return is the shorter perpendicular section of an L-shaped desk that branches off from the main surface. Returns typically measure 42"–54" wide and 24" deep. They are most commonly used as a secondary monitor station, printer shelf, or reference area. Returns come in left-hand or right-hand orientation. At FindOfficeFurniture.com, every listing clearly marks hand orientation so you order the correct configuration the first time.
