Bard 543-221-XBX - Heater Access Cover Assembly

Bard 543-221-XBX is an OEM heater access cover assembly used on Bard wall-mount HVAC equipment to close off the heater access opening while still allowing straightforward service access when maintenance is needed. As an exterior cabinet component, it helps protect internal heater components from weather and jobsite conditions and supports proper cabinet integrity when installed correctly. Finished in Beige textured enamel to match factory units. 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.
