Abstract: A chuck and lock system prevents the load on a flatbed truck from shifting at the destination during offloading. The system includes one or more extendable brace units or vertical stakes and a movable chuck and lock, which operates as a socket locking each extendable brace in place. The chuck and lock unit is attached to dunnage underneath the load. The units can be spaced on either side of the load where needed. The load is held on each side between the vertical braces adjacent to the load and which are adjusted for the height of the load. Straps are supported by the extendable braces and go over the load. At the destination, prior to unloading, all straps or lashings are removed or loosened. The vertical braces prevent the load from shifting sideways and causing an accident. The load is offloaded by a load lift.
