Bard 509-251 - Back Assembly

The Bard 509-251 Back Assembly is an OEM cabinet component used on select Bard wall-mounted air conditioners to restore the correct rear cabinet structure and fit at the building interface, helping support internal components and maintain proper airflow separation and weather protection. This back assembly is intended as a direct replacement when the original rear section is damaged, corroded, or compromised during service, and using a genuine Bard part helps ensure the cabinet lines up correctly with adjoining panels and factory openings. Confirm compatibility by matching your unit model and serial information to the Bard replacement parts list before ordering, since back assemblies can vary by series and cabinet configuration.
