The file includes an open top tub having casters on its legs. There are side hangers located at the sidewalls such that hanging files can be hung between the sides, and there are end hangers and a central hanger spaced between the ends such that hanging files can be hung between each end and the central hanger. The end hangers are removably secured in the tub such that they can be removed to facilitate the insertion of an integral door and interior end wall assembly. In the assembly, the door is slidably mounted to the end wall by means of interfitting channels and the end wall can be releasably secured to the tub at the end thereof. The end wall itself includes a hanger flange to serve the function of the removed end hanger.
An all-plastic module forms a letter-by-legal frame in which file folders can hang. The module is assembled from two identical end pieces and two identical side pieces. Casters can be attached to the module so it can roll on a floor or a desktop. The modules can be stacked. A lid can be detachably secured to a module to prevent dust from settling on the file folders therein.
An adjustable hanging file system for a drawer having side panels utilizes frame members comprised of spaced skirts with a connecting crown to thereby define a u-shaped cross section and bracket members inserted between the skirts to support the frame members. Additional hanging bracket members incorporated with cross rail frame members support the cross rail frame members on frame members attached to a file drawer.
