Abstract: An adaptable cargo rack system that is easily transformable between a plurality of modes for carrying different kinds of items and performing different kinds of tasks is provided. The cargo rack system provides mounting brackets and poles that interconnect via identical universal connectors that do not require tools to interconnect and move between a locked position and an unlocked position. The cargo rack system also provides a plurality of rails that extend between posts. Accordingly, the same cargo rack system can be transformed between a first framework mode, a second framework mode and an elongated mode to carry items that are rectangular and planar, bulky and boxy, and elongated, respectively.
