The HART COOLEY 671 10 06 wht is a one-way baseboard return air grille designed for residential and light commercial HVAC applications. Measuring 10 inches by 6 inches, this grille mounts at baseboard level to draw return air back into the duct system. The white finish allows it to blend with standard interior trim. HVAC installers and service technicians use this grille as a finished face for return air openings located along the lower wall or floor-wall junction, where low-profile return placement is required.
This grille is suited for residential forced-air systems where return air is routed through baseboard-level duct openings. The one-way airflow design directs return air in a single plane, making it appropriate for wall cavities or duct boots oriented in a single direction. It is a common choice in new construction and retrofit installs where space constraints limit return air placement to the baseboard zone.
Designed as an OEM-style replacement or new-construction grille for standard 10-inch by 6-inch baseboard return air duct openings in residential forced-air HVAC systems.
Installation is typically performed by a licensed HVAC technician or qualified installer. Power down the air handler or furnace before working on return air openings to prevent debris from entering the duct system during installation. Verify the rough opening dimensions match the grille face size before securing. Follow local mechanical codes for return air grille placement and clearances.
