The Bard 111-293BX supply air frame assembly is an OEM duct interface component used on select Bard wall-mounted package air conditioners and heat pumps to properly align, support, and seal the supply air outlet where the unit connects to the supply plenum or discharge duct. A solid, correctly fitted frame helps prevent air bypass and leakage that can reduce delivered airflow, create noise, or cause comfort complaints, especially in through-the-wall and exterior wall-mount installations where the duct connection is critical. This boxed assembly is intended as a direct replacement for the original factory part, so verifying the unit model and serial information before ordering is the best way to confirm correct fit.
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
