• CRV Exhaust BOP Assembly

The Bard 536-489 CRV Exhaust BOP Assembly is an OEM ventilation accessory used with Bard wall-mount equipment configured for CRV (commercial room ventilator) ventilation options, providing the correct exhaust block-off and plate arrangement needed to maintain proper airflow paths and building pressure control. If your unit has been modified in the field, damaged during service, or has a missing plate set behind the service access area, replacing with Bard part 536-489 helps restore factory-intended ventilation performance and fitment without guesswork. As with any ventilation component, confirm the unit model and vent option code before ordering so the assembly matches your specific Bard configuration.
