a bottom structure comprising a plurality of channels for return air flow from an interior of the railcar to the refrigeration unit; and
at least two top plates coupled to the bottom structure, wherein each of the top plates extends longitudinally along the bottom structure and is configured to rotate up and away from the bottom structure proximate one of the side walls of the pair of side walls;
wherein the at least two top plates are pivotally coupled to the bottom structure via one or more pivot rods coupled to a longitudinal edge of the bottom structure proximate one of the side walls of the pair of side walls, wherein lifting an edge of a top plate opposite the edge of the top plate pivotally coupled to the bottom structure causes the top plate to rotate to an upright position exposing the plurality of channels of the bottom structure.
