Abstract

A metal frame structure designed to fit and attach on top of a half height ISO open top container. This extends the vertical height to which general cargo can be loaded and secured in a half height open top container. The cargo extension frame also serves as a securing structure for cargo items of irregular sizes and shapes or in circumstances where the upper portion of a cargo item may be top heavy or difficult to block and brace. When the cargo extension frame is not in use, the four vertical legs can be folded parallel to the underside of the left and right side longitudinal rails to facilitate handling and storage.
