A system comprised of vertical posts and horizontal boards or panels designed to be mounted around the perimeter of a flatbed truck or trailer. This assembly provides a containment structure that prevents cargo from shifting or falling off during transport. An example would be installing wooden planks within metal uprights along the edges of a trailer to secure lumber.
These add-ons are vital for safe and efficient hauling of loose materials or oddly shaped loads. They offer enhanced cargo security, preventing loss and minimizing the risk of accidents. Historically, such structures have evolved from simple rope restraints to more robust, purpose-built solutions that improve both the carrying capacity and safety profile of flatbed vehicles.
