A cargo management system for a vehicle having a cargo area such as a pickup bed is disclosed. The system includes a rail attachable to the interior surface of the cargo box inner panel, at least one reinforcement plate positionable against the outer surface of the inner panel, and a plurality of fasteners for holding the rail to the inner panel backed by the reinforcement plate. At least one cleat is fitted to the rail. The cleat can be moved and selectively positioned on the rail. The rail has a rail portion and a body portion. The body portion is positioned through a slot formed in the bedliner. The body portion of the rail includes a base and a pair of opposed side walls connecting the base with the rail portion. The body portion of the rail may include one or more interior walls between the base wall of the body portion and the rail portion. Each reinforcement plate has apertures to accommodate multiple mechanical fasteners, thus eliminating the multiple reinforcement plates of the known technology. Each reinforcement plate includes a plurality of reinforcement segments and reinforcement segment bridges. Each reinforcement segment is attached to an adjacent reinforcement segment by a reinforcement segment bridge.
