The RECTORSEAL 19FG20X24 is a return air filter grille designed for 20 x 24 inch rough opening sizes and built to accept standard 1-inch deep filters. Constructed from heavy-duty steel with a white powder-coat finish, the unit resists corrosion while maintaining a clean, low-profile appearance on ceilings and sidewalls. A hinged, removable face panel allows fast filter access without removing the frame from the wall or ceiling. This grille suits residential and light commercial HVAC systems where dependable return airflow and easy serviceability are required. HVAC technicians and installers are the typical end users.
