ABSTRACT:
A vertical file assembly which is easy and less costly to manufacture with injection molding techniques has (1) a divider unit with spaced apart dividers rising from an integral base panel to form compartments for books, catalogs, file folders and documents and (2) two wedge-shaped adapters each with a pair of barbed projections projecting inwards from an upper edge. These projections are inserted in receiving slots and latched in apertures formed in the bottom of the base panel of the divider unit. When the adapters and divider unit are assembled, the base panel slants upward from front to back to elevate each divider a certain measure above the preceding divider. The wedge-shaped adapters also have tabs with ledge portions which slide along the sidewalls and are caught in niches in the sidewalls of a supporting letter tray.
