The RECTORSEAL 150MW4X14 is a two-way stamped steel floor grille designed for installation in 4-inch by 14-inch floor duct openings. The stamped louver configuration directs conditioned air evenly in two opposing directions, supporting balanced airflow distribution across the served zone. A white powder-coated finish provides corrosion resistance and a clean, consistent appearance suited to residential interiors. This grille is installed by HVAC technicians and mechanical contractors in forced-air systems where floor-mounted supply outlets are required and extended airflow span is a design priority.
This floor grille fits standard residential forced-air HVAC applications where floor duct openings measure 4 inches by 14 inches. The two-way louver pattern is well suited to rooms where conditioned air needs to travel in opposing directions from a single supply point, such as along exterior walls or under windows. It integrates into new construction and retrofit installations alike.
Designed as an OEM-style replacement or new-installation floor grille for residential forced-air HVAC systems with 4-inch by 14-inch floor duct openings.
Installation is performed by licensed HVAC technicians or qualified mechanical contractors. The supply air system should be shut down before removing an existing grille or setting this unit in place. Secure the grille per local mechanical code requirements and verify the duct opening dimensions before installation to ensure a flush, rattle-free fit.
