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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOne-piece steel construction for rigidity and long service life\u003c\/li\u003e\n  \u003cli\u003e1\/3-inch spaced fins angled at 20 degrees for high free area and airflow efficiency\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch margin turnback for a clean, finished wall appearance\u003c\/li\u003e\n  \u003cli\u003eInstalls with fins upward or downward to conceal ductwork as needed\u003c\/li\u003e\n  \u003cli\u003eBright white enamel finish coordinates with standard painted trim\u003c\/li\u003e\n  \u003cli\u003eComplementary return air grille for HART COOLEY Model 654 and Model 664 supply grilles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with HART COOLEY Model 664 and Model 654 supply grilles.
