Hart Cooley 821-14x4 Supply Register with Adjustable Vertical Blades 14 X 4 Inches

Product Description

The Hart Cooley 821-14x4 is a sidewall supply register designed for light commercial HVAC applications. It features a single-piece construction with vertical adjustable face bars that let technicians direct airflow where it is needed. The unit ships in a nominal 14 x 4 inch size and measures 15.875 inches by 2.25 inches by 5.875 inches overall. HVAC installers and service technicians rely on this type of register to manage conditioned air distribution in offices, retail spaces, and light commercial buildings. The steel body is finished in bright white enamel, making it easy to match standard ceiling and wall trim. The multi-shutter damper provides horizontal adjustable control over airflow volume, giving the installer a simple way to balance the system after installation. Fin spacing is 0.75 inches, which supports even air distribution across the face of the register. Single deflection keeps the airflow pattern consistent and predictable. The actuation type is a horizontal adjustable multi-shutter valve, which is a common and reliable damper mechanism found in commercial-grade supply registers. This register is part of the Hart Cooley 821 series, a line known among HVAC professionals for durable steel construction and clean white enamel finishes that hold up in high-traffic commercial environments. Whether you are replacing an existing unit or completing a new installation, the 821-14x4 is a straightforward drop-in choice for standard sidewall supply openings in light commercial ductwork systems. Contractors, mechanical installers, and HVAC service teams working on forced-air systems will find this register easy to install and reliable in daily operation.
