A multi-position endgate system includes a storage box wall and a storage box floor. A tailgate is mounted relative to the storage box floor and is pivotal about a tailgate axis. The tailgate is moveable between a fully-closed position proximal to the storage box wall and a fully-open position distal from the storage box wall. A cable mechanism has a first end pivotally attached to the tailgate and a second end pivotally attached to the storage box wall. A channel hook is attached to either the tailgate or the storage box wall at a connector. An arcuate ledge is spaced from the connector, by an arm, and defines a groove. The cable mechanism may be passed or routed through the groove of the arcuate ledge to selectively hold the tailgate in an intermediate position between the fully-closed and fully-open positions.
