Bard 509-398 - Supply Box Back Assembly

Bard part 509-398 is an OEM supply box back assembly used in Bard wall-mount air conditioner cabinet ductwork, forming the rear section of the supply air box that helps contain and direct discharge airflow where it belongs. If your existing supply box back is bent, corroded, or damaged during service, replacing it with the correct factory assembly helps restore proper alignment with the supply air frame and reduces the chance of air bypass, rattles, or fitment issues when reinstalling adjoining panels and back sections. Because this is a model-specific cabinet and airflow component, confirm the unit model and serial number and verify the part callout in your Bard parts manual before ordering to ensure an exact match.
