Brackets attach to the truck box side wall in parallel therewith. Posts on each bracket as well as sockets defined by the brackets receive a weldment at each stanchion lower end the weldments having keyhole openings for post reception and pins for insertion into the bracket sockets. A flexible lock automatically engages a post on the stanchion to prevent accidental upward displacement of the stanchion during truck travel.
