A modular truss system includes six-way box connectors to which truss beams can be bolted and pinned together in a wide variety of configurations and to any or all of the six identical faces. When it is desired to deactivate the label or tag, the tag or label is subjected to tearing. The method is particularly suitable for machines used to level flat metal products. In another embodiment, case goods may employ a collapsible frame as described herein.
