The Bard 137-336 Return Fill Plate is an OEM sheet metal airflow closure part used in the return air section of select Bard wall-mount packaged HVAC units. This plate helps maintain the correct return air path by covering an unused opening or gap so the unit pulls air where it is intended to, which supports proper circulation, filtration performance, and overall system operation. If you are replacing a damaged or missing plate after service work, using the correct Bard part number matters for alignment with the cabinet and adjacent return air components, so confirm your model and serial compatibility before ordering.
