Abstract: A cargo tie down system for use in securing either containerized cargo or a containerized cargo conveyance system to a transport vehicle. The cargo tie down system includes a cargo tie down adapter having a housing and a cargo ring coupled to the housing for use in tying down noncontainerized cargo. The cargo tie down system also includes a mounting apparatus adapted to be attached to the containerized cargo conveyance system that includes a selectively rotatable stud having a head with outwardly extending wings. The housing includes a receptacle adapted to selectively receive and retain the stud of the mounting apparatus to secure the containerized cargo conveyance system to the transport vehicle when containerized cargo is to be transported without requiring removal of the cargo ring.
