Vertical file cabinets are the most widely used filing method. Vertical files solve two fundamental problems: limitations on space and long term storage. Vertical files require minimal floor space, and they are the best for storage requiring infrequent retrieval. Vertical files are available in 2-, 3-, 4- and 5-drawer heights, as well as three different widths: 25″, 26-1/2″ and 28-1/2″. High side walls accommodate hanging files and eliminate the need for hanging file frames. A fully adjustable and removable follower block is standard in every drawer for neat filing.
