Hart Cooley 43621 Hc 654 12 X 6 Inch Baseboard Register Bright White Enamel Steel with Volume Control Damper

Product Description

The Hart Cooley 43621 is a 654 Series baseboard register designed for residential sidewall and baseboard HVAC applications. This 1-piece steel register measures 12 inches by 6 inches nominally, with overall dimensions of 13 and 1 quarter inches by 1 and 15 sixteenths inches by 7 and 1 quarter inches. It ships in cases of 20 units, making it a practical choice for contractors and HVAC professionals stocking up for new construction or retrofit projects. The register features a bright white enamel finish that blends cleanly with standard residential trim and drywall. The steel construction provides durability and resistance to everyday wear in high-traffic living spaces. A 20-degree fin angle and 1 third inch fin spacing are engineered to distribute airflow efficiently across the room. The unit is rated for 290 CFM at 1000 FPM velocity, giving installers a reliable performance benchmark when sizing and placing registers in a forced-air system. One of the key functional features of the Hart Cooley 43621 is the integral positive volume control damper. This built-in damper allows occupants or technicians to adjust airflow directly at the register without a separate damper assembly. That means fewer parts to source and a cleaner installation overall. The 654 Series is a well-established line in the Hart Cooley catalog, trusted by HVAC contractors for its consistent fit and finish in residential builds. Whether used in new construction or as a replacement register in an existing system, this baseboard register delivers straightforward performance and easy installation. The 1-piece design reduces installation time and ensures a uniform appearance at the wall or floor opening.
