Part of the 411 Series, this steel floor diffuser fits a wall opening of 4 inches by 12 inches and has an overall face size of 5.5 inches by 13.5 inches. It is built to deliver conditioned air from floor-level supply registers in forced-air heating and cooling systems. HVAC installers and contractors rely on floor diffusers like the 411-4x12w to direct airflow efficiently into living spaces, improving comfort and circulation throughout a room. The white finish blends cleanly with standard flooring and trim, making it a practical choice for new construction and replacement installs alike. The steel construction provides durability underfoot and resists the wear that comes with floor-level placement. This diffuser is compatible with standard residential ductwork and is suited for use in bedrooms, hallways, living areas, and other spaces where floor supply registers are part of the duct layout. When ordering, the listed size refers to the approximate wall or floor opening required, not the overall face dimensions. Always refer to the submittal drawing for exact cutout measurements before installation to ensure a proper fit. The 411 Series from Hart Cooley is a well-established line of supply diffusers used by HVAC professionals across a wide range of residential and light commercial projects. Replacement of worn, damaged, or discolored floor registers is a common service call, and the 411-4x12w is a direct fit for standard 4 inch by 12 inch duct openings.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFits a 4 inches x 12 inches wall or floor opening with an overall face size of 5.5 inches x 13.5 inches\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in floor-level supply register applications\u003c\/li\u003e\n\u003cli\u003eWhite finish suits standard residential interiors and works for both new installs and replacements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Hart Cooley 411-4x12w delivers reliable floor-level supply air distribution in residential and light commercial HVAC systems.
