Abstract: Tailgate-mounted apparatus for stabilizing loads being carried in or supported by a pickup truck in a variety of configurations. The apparatus includes a bar and a pair of end supports for the bar mounted to the tailgate inside surface adjacent tailgate side edges and near the tailgate upper edge. The bar is detachably mounted to the end supports, and extends along the tailgate inside surface in spaced relationship thereto generally between the side edges. A pair of article clamping elements, which generally resemble bookends, are slidably attached to the bar and provided with locking devices for selectively securing the article clamping elements at various positions along the bar. In one position, typically employed when the tailgate is in its horizontal lowered position, the clamping elements extend generally perpendicular to the tailgate surface and upwardly for stabilizing articles supported by the bed and by the bar.
