• Vent Option Door Assy-Stainles

Bard part number S553-449 is an OEM vent option door assembly made from stainless steel for Bard wall mounted HVAC units equipped with the vent option. This door is the service replacement used to close and seal the vent opening when required, helping the unit maintain correct airflow and outdoor air control, reduce unwanted air leakage, and support proper operation in applications like schools, modular buildings, and light commercial spaces. If your existing vent door is damaged, corroded, or not sealing correctly, replacing it with the correct Bard S553-449 assembly helps restore the intended ventilation function and fit with the factory vent hardware on compatible cabinets.
