Bard part 535-398BX is an OEM copper chase left assembly built for left-side installation on select Bard wall-mount HVAC units, providing a protected routing path for refrigerant tubing and wiring as they pass through the cabinet. Replacing a damaged or missing chase helps prevent rubbing, kinks, and exposure that can lead to leaks, electrical issues, or nuisance service calls, especially in harsh environments. This stainless steel chase assembly is designed to match Bard factory fit and clearances, so the line set and harness stay properly supported during operation and service. Confirm left-hand orientation and unit model compatibility before ordering to ensure proper 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.
