• Back Assembly

The Bard S509-281 Back Assembly is an OEM structural sheet metal component that forms the rear framework of select Bard wall mounted HVAC units, providing the rigid mounting surface and alignment needed for proper fit-up of internal sections and exterior panels. When the original back structure is bent, corroded, or damaged from handling, replacing it with the correct Bard factory part helps restore cabinet integrity, supports proper sealing and airflow paths, and reduces the chance of vibration issues or misaligned service access. Match S509-281 to your unit model and serial information or the correct Bard parts list to confirm compatibility before ordering.
