The RECTORSEAL 150MW4X8 is a stamped steel 2-way floor supply grille sized for 4-inch by 8-inch duct openings. It features a two-way louver face that gives the installer directional control over supply airflow delivery at the floor level. The white powder-coated finish resists corrosion and holds its appearance in occupied spaces. This grille is installed by HVAC technicians and mechanical contractors in residential forced-air systems where compact, low-profile floor supply is required.
This floor grille fits into standard 4-inch by 8-inch floor duct openings and delivers supply air in two adjustable directions, making it well-suited for perimeter heating and cooling layouts common in residential construction. The stamped steel body provides structural durability underfoot. Its white finish blends with standard residential flooring and trim finishes typical of new construction and retrofit applications alike.
Designed as an OEM-style replacement or new-installation floor supply grille for residential forced-air HVAC systems with 4-inch by 8-inch floor duct openings.
Installation is performed by licensed HVAC technicians or qualified mechanical contractors. Power down the air handler or furnace before removing an existing grille and inspecting the duct collar. Ensure the duct opening dimensions match the grille neck size before securing. Follow applicable mechanical codes for supply register placement and clearance requirements.
