Adjustable rods for use in a filing system are disclosed. An example rod includes an elongated body having a first end and a second end, a first hook extending from the first end, and a second hook extending from the second end. In addition, the example rod includes a first resilient member having a first length. The first hook is coupled to the elongated body via the first resilient member, and the first length of the first resilient member is automatically adjustable during movement of the rod.

A secure document receptacle for use in file cabinets having slidable drawers with laterally spaced support rails for removable supporting file folders. The secure document receptacle has a single support brace along the top edge with downwardly opening channels for removable engagement with the drawer support rails. The receptacle has a closed top edge and openings to the interior of the receptacle on the side edge or the bottom edge of the receptacle. Documents can only be inserted and removed via the open side or bottom edges. The receptacle must be partially or completely removed from the drawer support rails before a document can be removed from the receptacle. This interrupts contact between the brace channels and the support rails, an event which can be detected by cabinet sensing circuitry.

A hanging file folder for mounting to a pair of spaced apart rails is disclosed. The file folder has a first and second rod with a pair of hook portions on opposing ends thereof for engaging the pair of spaced apart rails. The file folder body has first and second walls forming a pocket for holding materials therein, and is assembled such that the pocket is suspended between the first and second rods. At least one of the first and second rods includes a resilient structure for permitting at least one of the hook portions to move longitudinally and adjust an effective length of its rod for accommodating variances in the angle at which folders are mounted on the rails. The resilient structure may include a tension spring, for example. The hook portions may be movably mounted to the rod and may include the resilient mechanism.
