Abstract: A quick-release, horizontal logistic track having a coupling mechanism that allows two such quick-release logistic tracks to interlock so as to effectively form a continuous track that varies in length as a section of track is added or removed from the series. Installed, the multiple sections of quick-release logistic track become one integrated track that is flush from end to end on the same sidewall. The quick-release logistic track has two integral couplings that consist of a male coupling and a female coupling on opposing ends enabling the male end of a newly installed track in the series to be coupled to a female end of a separate track that is already anchored in a vertical logistic post slot. As the newly installed track's male end is coupled to the anchored female end the newly installed track's opposing female end is then anchored to an adjacent vertical logistic post slot. This method is repeated until the desired length of quick-release logistic track is satisfied.
