- Vent Option Door Assy-Aluminum
The Bard S552-456 Vent Option Door Assy-Aluminum is an OEM vent option access door assembly used on select Bard wall-mounted packaged units to properly close and protect the optional ventilation opening while supporting correct airflow through the vent section when the vent kit is installed. This replacement door helps restore the unit’s intended ventilation operation and keeps the vent opening aligned and sealed the way Bard designed it, which is important for reliable outdoor air control and overall cabinet integrity. As a genuine Bard part, S552-456 is built to match the original fit and mounting points shown in Bard replacement parts documentation for compatible wall-mount series, making it a dependable choice when the existing vent door is damaged, missing, or no longer closing correctly.
