Abstract: A movable bulkhead for a cargo carrying container includes a fixed panel and one or move movable panels. The movable panels are movable between a first position in which they are coplanar with the fixed panel so as to define a maximum cargo volume within the container, and a second position in which the movable panels are spaced from the fixed panel to thereby reduce the cargo volume within the container. Load bars are adapted for engagement with the side walls of the container for bracing the movable panels against movement when such panels are in their second position, and are adapted for storage behind the movable panels when such panels are in their first position and the load bars are not in use.
