ABSTRACT:
A knockdown file cart which can be easily assembled without tools or fasteners, and which is rigid when assembled. The cart has two upstanding side panels with metal strips at their edges which form troughs. Two end panels have inwardly projecting flanges which can be slid down in the troughs and releasable locked in place by a spring tab on each flange that projects into a slot in the strips. A bottom panel can be inserted to form the bottom of the cart and further improve its rigidity.
