Hart Cooley 821-30x14 White Steel Sidewall Ceiling Return Air Grille 30 X 14 Inches 672 Series

Product Description

The Hart Cooley 821-30x14 is a white steel return air grille designed for sidewall and ceiling HVAC applications. It fits a wall opening of 30 inches x 14 inches and has an overall face size of 31-3/4 inches x 15-3/4 inches. This grille belongs to the Hart Cooley 672 Series, a line trusted by HVAC contractors and mechanical installers for consistent performance and clean aesthetics. Return air grilles are a critical part of any forced-air HVAC system. They allow conditioned spaces to push air back through the ductwork to the air handler or furnace. A properly sized return grille helps maintain balanced airflow, reduces static pressure, and improves system efficiency. The 821-30x14 is built from all-steel construction, making it durable enough for long-term residential and light commercial use. The fins are spaced at 1/2 inch intervals and set at a 40-degree angle, which maximizes free area while keeping the opening visually clean. A wider free area means less restriction on return airflow, which reduces strain on the blower motor and helps the system move the correct volume of air. The grille features a 5/16-inch margin turn back and a bright white powder-coat finish that blends easily with standard interior walls and ceilings. HVAC technicians and installers use this grille as a straightforward drop-in replacement or new-installation component in residential homes, apartments, offices, and light commercial buildings. The screw hole placement should be verified against the manufacturer submittal drawing before installation, as dimensions shown are approximate. This grille is compatible with standard duct openings in that size range and installs with visible face screws. It is a reliable, no-frills return air grille for professionals who need dependable airflow management.
