The FastRak Archive Shelving system offers flexible and economical configuration options, allowing you to purchase one free-standing starter unit and then easily extend rows of shelving by adding one or more Add-On units to the starter. Built from industrial-strength FastRak™ components designed to support even your heaviest archive boxes, these units accommodate either 15" deep or 24" deep archive boxes and are priced with or without boxes. Choose from 8' tall units with 4 shelves or 10' tall units with 5 shelves. The 18" and 36" deep units are ideal for standard archive boxes (typically 15"D x 12"W x 10"H), while the 24" and 48" deep units suit banker boxes (typically 24"D x 12"W x 10"H).
