Bard 509-121 - Back Assembly

Bard part number 509-121 is an OEM Back Assembly used on select Bard wall mounted HVAC units to restore the structural back section of the cabinet and help keep internal components properly supported and aligned. When a back assembly is bent, rusted, or damaged from handling or weather exposure, replacing it with the correct Bard factory part helps maintain the unit’s intended clearances, panel fit, and overall cabinet integrity for reliable service. Verify the exact match by confirming your Bard model and serial number against the unit parts list before ordering, since back assemblies can vary by model family and revision.
