A top casting for stacking frames of cargo containers. The top casting has an aperture for stacking and top picking non-standard cargo containers. The top casting also has a cavity that is configured to allow for the insertion and rotation of a standard top-picking device. The top casting positions the aperture near the outboard wall of the cargo container to reduce moment stresses caused by stacking and lifting. The outboard wall of the casting is provided with an internal recess adequate to allow the rotation of a lifting device head after it has been inserted into the cavity of the top casting. The aperture of each top casting is capable of receiving a top picking device and its axis is located at a distance no greater than 3 inches from the outboard wall of the cargo container so as to position the aperture as near as possible to the stacking post.
