Abstract: This disclosure relates to a barrier assembly that can be selectively secured near an opening of a cargo container and selectively deployable near the opening of the cargo container (e.g., along the rear and/or side of the cargo container) to control access to the space therein and to help secure cargo contained within the space. The barrier assembly can include one or two panels that can permit the barrier assembly to wrap, bend, or flexibly extend around cargo. In at least some examples, at least one panel can be hingedly affixed to a side of the cargo container, such that the panel can rotate between a stowed position and a deployed position. In examples, the panel is also slidably connected to the side of the cargo container, such that a fore-aft position of the panel can be adjusted and customized to the cargo.
