The HART COOLEY 421m0412w is a heavy-gauge steel floor register designed for residential and light commercial HVAC duct systems. It measures 4 inches by 12 inches and ships in a Bright White enamel finish. Built from all-steel construction with welded joints, this register is engineered to hold up under foot traffic without flexing or rattling. Multi-angle adjustable fins allow the technician or installer to direct airflow as needed for the space. A foot-operated dial control lets occupants adjust airflow without bending down. The rolled fin edges reduce the risk of cuts during handling and installation.
This floor register fits standard 4-inch by 12-inch floor duct openings in forced-air heating and cooling systems. It is suited for residential applications including living rooms, hallways, and bedrooms where a durable, clean-looking register is required. The stamped steel face and enamel finish hold up to regular cleaning and normal household wear. HVAC installers and service technicians typically specify this register for new construction and retrofit duct termination work.
Designed as an OEM-style replacement or new-installation floor register for standard 4-inch by 12-inch floor duct openings in residential forced-air HVAC systems.
Installation is typically performed by an HVAC technician or general contractor during duct finishing. Shut down the HVAC system before removing an existing register or cutting a new floor opening. Ensure the rough opening matches the 4-inch by 12-inch duct collar dimensions before setting the register in place. No special tools are required beyond standard hand tools; follow local mechanical codes for register placement and minimum clearance requirements.
