The Bard 113-647BX insulation bracket (boxed) is an OEM internal support component used in Bard wall mounted HVAC equipment to hold insulation in the correct position and keep it from shifting into moving parts or critical air paths. A properly fitted insulation bracket helps maintain intended airflow and sound control inside the cabinet while reducing the risk of insulation rubbing, tearing, or interfering with service access. Use Bard 113-647BX when replacing a damaged, missing, or corroded bracket during repairs to restore factory fit and secure mounting.
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.
