The HART COOLEY 60gh 30 24 wht is a horizontal sidewall grille designed for use in residential and light commercial HVAC air distribution systems. Measuring 30 inches wide by 24 inches tall, this white grille installs on sidewall openings to control the direction of conditioned air into a room. Its horizontal blade orientation promotes wide lateral air spread, making it well suited for rooms where ceiling height or duct placement calls for sidewall supply or return applications. HVAC technicians and installers handle this type of fitting as a standard part of forced-air system rough-in and finish work.
This grille is intended for sidewall installations in forced-air heating and cooling systems. The horizontal configuration supports supply or return air applications where airflow needs to travel across the room at a consistent elevation. At 30 inches by 24 inches, it fits larger duct openings typically found in commercial spaces, open floor plans, or high-capacity residential systems. It is finished in white to coordinate with standard interior wall and ceiling finishes.
Designed as an OEM-style sidewall grille replacement or new-installation fitting for forced-air HVAC systems requiring a 30-inch by 24-inch horizontal sidewall grille opening.
Installation is typically performed by a licensed HVAC technician or mechanical contractor. Power down the air handling system before beginning any ductwork or grille installation. Verify the rough opening dimensions match the grille face size before securing to the wall surface. Follow applicable local mechanical codes and manufacturer fastening guidelines when mounting the grille to drywall or framed openings.
