Abstract: A cargo load-lock is provided having a blocking member and a pair of braces. The cargo load-lock can be used to limit shifting of freight during shipping. In the first preferred embodiment, the blocking member is a rigid structure, such as a 2.times.4. The blocking member is secured to opposing trailer sidewalls by the two braces. A brace is positioned at opposite ends of the blocking member, and is then secured to the trailer. Each brace includes a base and a sleeve. The sleeve receives opposite ends of the blocking member. Opposite the sleeve, the base includes an adhesive which provides a bond between the brace and the sidewall. Once the braces are secured, the cargo load-lock is in place. No tools are required. To collapse the cargo loadlock, the blocking member is first removed. This can be accomplished by prying open a portion of the sleeve. This is facilitated by perforations which extend in a U-shaped design along the top of the sleeve.
