<p>The document storage system has cover plates which are thicker than the plastics support rods (13), and apertures slightly larger than the rods. It includes rectangular cover plates (1). From the longitudinal side, the plate has two rod receiving apertures (3) the spacing of which is equal to the usual perforation of a standard filing system. The slotted aperture (3) in the far part of the plate width runs into a slot (5). The end edge (4) is approx. in the centre of the plate width.</p> |
