Hart Cooley 75033 821 Series Supply Register 18x10 Inches Bright White Enamel Steel Sidewall Vertical Fin

Product Description

The Hart Cooley 75033 is a 821 Series supply register designed for sidewall installation in residential and light commercial HVAC systems. This register measures 18 inches wide by 10 inches tall, with overall dimensions of 19 and 7 eighths inches wide by 11 and 7 eighths inches tall by 2 inches deep. It is constructed from durable steel with a bright white enamel finish that blends cleanly into standard interior wall surfaces. The vertical fin design and adjustable face bar give HVAC technicians and installers precise control over airflow direction. The face bar can be repositioned to direct conditioned air horizontally across the room, helping balance airflow distribution without additional hardware. The 3 quarter inch fin spacing is a standard configuration that supports consistent, even air delivery across the supply opening. This register includes a multi-shutter damper with a horizontal multi-shutter valve actuator, allowing the technician or building occupant to regulate the volume of airflow directly at the register face. This is a key feature for zoning comfort in individual rooms. The 1-piece construction keeps installation simple and reduces the chance of component misalignment during mounting. At 3.930 pounds, the unit is solid and sturdy without being difficult to handle during wall installation. The Hart Cooley 821 Series is a widely recognized product line used by HVAC contractors across the country for new construction and retrofit applications. This register is compatible with standard duct openings and is suited for use in offices, retail spaces, schools, and residential buildings. Whether you are replacing a worn register or specifying units for a new system, the 75033 delivers reliable performance in a clean, professional package.
