Bard 552-456BX - Vent Option Door Assembly
The Bard 552-456BX Vent Option Door Assembly is an OEM replacement door used on Bard wall-mounted HVAC units equipped with the ventilation option, helping the unit maintain proper outside-air control and cabinet sealing when the vent section is opened and closed. Built to Bard fit and alignment standards, this assembly is the right choice when a vent door is damaged, bent, or no longer seals correctly, which can lead to unwanted air leakage and performance complaints. As a Bard factory part, 552-456BX is intended to match the original vent option door configuration used on compatible Bard equipment, so confirm the part number against your unit model and serial before ordering to ensure correct fit.

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.
