The RECTORSEAL 19H20X16 is a stamped steel return air grille designed to allow unrestricted airflow back to the HVAC system through sidewall or ceiling return openings. The fixed stamped blade face provides a clean, consistent appearance while supporting adequate return air volume for the connected system. The face dimension measures 20 inches by 16 inches, making it suitable for larger rectangular return openings that require increased airflow capacity. A white powder-coat finish delivers corrosion resistance and long-term appearance stability in both residential and light commercial installations.
This grille is used in residential and light commercial HVAC systems where sidewall or ceiling return air intake is required. It fits larger rectangular cutouts and is appropriate for central air, heat pump, and forced-air furnace systems that need a durable, low-profile return grille. The stamped face design keeps debris out while maintaining low resistance to return airflow.
Designed as an OEM-style replacement or new-installation return air grille for residential and light commercial forced-air HVAC systems requiring a 20-inch by 16-inch face opening.
Installation is typically performed by a licensed HVAC technician or qualified contractor. Power down the HVAC system at the thermostat and disconnect power at the air handler or furnace before removing or installing a return grille. Verify the rough opening dimensions match the grille face size before fastening. Follow local mechanical codes for return air grille placement and clearance requirements.
