The Hart Cooley 821-24x10 is a heavy-duty steel supply register built for sidewall installation in light commercial HVAC systems. This single-piece unit measures 24 inches wide by 10 inches tall at the nominal size, with an overall footprint of 25-7/8 inches wide by 11-7/8 inches tall and 2 inches deep. It is finished in bright white enamel, giving it a clean, professional look that blends into standard commercial interiors. The register features vertical fins spaced at 3/4 inches apart, allowing precise horizontal airflow direction from the face of the unit. An adjustable face bar lets technicians fine-tune the air deflection angle after installation, making it adaptable to different room layouts and comfort zones. The built-in multi-shutter damper operates with a horizontal multi-shutter valve mechanism, giving HVAC professionals control over airflow volume directly at the register. This is a significant advantage in zoned systems or spaces where balancing airflow between rooms is critical. The 821-24x10 is rated for face velocities between 400 and 2000 feet per minute, with an air flow rating ranging from 530 to 2640 CFM. Pressure loss ranges from 0.01 to 0.249 inches of water column across that operating range, making it suitable for a wide range of supply duct configurations in light commercial applications. The unit weighs 5 pounds and is constructed from durable steel for long service life. HVAC installers and service technicians working on commercial builds, tenant improvements, or retrofit projects will find this register reliable and straightforward to install. It is part of Hart Cooley's established 821 series, a trusted line of sidewall and ceiling registers used widely in commercial construction. The bright white enamel finish requires no additional painting and resists scuffing during installation.
The Hart Cooley 821-24x10 supply register delivers reliable airflow control and professional finish quality for light commercial sidewall HVAC installations.
