The HART COOLEY 671 12 06 wht is a one-way baseboard return air grille designed for residential and light commercial HVAC duct systems. Measuring 12 inches by 6 inches, this grille mounts at baseboard level to draw return air back into the ductwork efficiently. The white finish blends with standard interior trim and drywall. HVAC technicians and installers use this grille where low-wall or baseboard return openings are required, particularly in forced-air heating and cooling systems where floor or wall space constraints make standard high-wall returns impractical.
This baseboard return grille fits low-sidewall or baseboard duct openings in residential forced-air systems. The one-way airflow design directs return air horizontally into the duct opening. Typical installations include hallways, bedrooms, and living areas where baseboard-level return air collection is part of the system design. The 12-inch by 6-inch face size suits standard residential duct rough openings of the same nominal dimensions.
Designed as an OEM-style replacement or new-installation baseboard return grille for residential forced-air HVAC systems with 12-inch by 6-inch nominal return air openings.
Installation is typically performed by a licensed HVAC technician or sheet metal installer. Power down the air handler or furnace at the disconnect before opening ductwork or removing existing grilles. Verify the rough opening dimensions match the grille face size before fastening. Secure the grille to the wall or duct frame using appropriate screws; do not over-tighten fasteners into drywall without proper anchoring.
