Bard 543-221-4BX - Heater Access Cover Assembly
The Bard 543-221-4BX is an OEM heater access cover assembly used on Bard wall mount HVAC units to restore the proper exterior seal and safe service access to the electric heater compartment during maintenance and inspection. As an EXTERIOR CABINET COMPONENT, it is finished in Buckeye Gray textured enamel to match factory units, helping maintain the unit’s weather protection and overall cabinet integrity once installed. Ensure this matches the color of your Bard unit for seamless replacement. Exterior panels with enamel cabinet paint coating have been tested to withstand over 1000 hours of salt spray tests per ASTM B117-03. This listing is for the panel only. Reuse your existing fasteners, clips, and hardware.

What does the "BX" suffix mean?
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.
