Abstract
Abstract A ladder rack for pickup trucks mounted in a detachable manner along one side of truck box. A pair of stanchions each having upper ends provided with arms for ladder support. 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.
