Abstract: A lateral file having a cabinet structure which provides improved rigidity against racking, including an improved upright boxlike housing having an improved base associated therewith. The housing has opposed sidewall structures which are defined by identical one-piece monolithic structures each having a generally planar and upright exterior side wall with a pair of channel-like uprights fixed to an inside surface thereof and extending vertically along the exterior side wall adjacent opposite edges thereof. The upright channels and the exterior side wall are formed as a monolithic one-piece structure from a monolithic piece of sheet steel, such as by roll forming. The sidewall structure is generally symmetrical about a vertically extending centerline so that identical sidewall structures can define both the right and left sides of the housing.
