Air distribution assembly

An air distribution assembly primarily designed to distribute conditioned air, for cooling or the like within a defined space such as a truck body or railroad car. The assembly includes an air conduit of elongated or otherwise predetermined configuration extending along a wall surface of the defined space and including one or more vents formed therein. Each one of the vents is defined by a flap removably disposed from the air conduit itself so as to define an aperture from which the conditioned air is distributed from the conduit into the defined space. Connection elements each comprising two connector portions are mounted on the air conduit for removable attachment to the wall surface of the defined space and also mounted in removable, interconnecting relation between the vent flap and the surrounding edge of the aperture defined by the vent flap so that the various flaps can be displaced or disposed in closed relation thereby regulating the distribution of air within the defined space.
