• Upper Back Assembly

Bard part number S509-411 is an OEM Upper Back cabinet component used on select Bard wall mount air conditioner units to restore the correct cabinet structure, panel alignment, and equipment protection at the rear of the unit. This replacement upper back assembly helps keep the cabinet properly sealed and supported so internal components remain positioned as designed, which is especially important after corrosion damage, impact, or service work that distorted the original panel. As a genuine Bard replacement part, S509-411 is intended to match factory fitment for compatible models, but you should confirm applicability using the unit model and serial number before ordering.
