Hart Cooley 43664 Baseboard Return Air Grille 24x8 White

Product Description

The HART COOLEY 43664 is a baseboard return air grille designed for residential and light commercial HVAC ductwork systems. Built from one-piece steel construction, it features 1/3-inch spaced fins set at a 20-degree angle, delivering exceptional free area for efficient return airflow. The 7/8-inch margin turnback gives a clean, finished appearance at the wall opening. A bright white enamel finish ensures it blends with standard painted baseboard trim. Licensed HVAC technicians and installers use this grille as a fixed return air face at low-wall or baseboard register locations. It installs with fins oriented upward or downward to best conceal the duct opening behind it.

The 43664 is suited for residential HVAC applications where a low-profile baseboard return grille is needed. It fits a wall opening of 24 inches wide by 8 inches high, with an overall face size of 25-3/4 inches by 9-3/4 inches. This grille is intended to serve as the return air complement to HART COOLEY Model 654 or Model 664 supply grilles, making it a natural pairing choice when matching an existing supply register in the same installation.

Installation Notes

Installation is typically performed by a licensed HVAC technician or qualified installer. Power down the air handling system before cutting or fitting the wall opening to prevent debris from entering the duct. Secure the grille to the wall surface using the margin turnback as the mounting flange, and orient fins upward or downward based on the desired airflow direction and duct concealment. No field modification of the fin angle is recommended.
