Sized at 4 x 8 inches with a duct opening of 7-7\/8 x 3-15\/16 inches, it fits standard floor duct cutouts and handles up to 130 CFM of airflow. The faceplate is precision stamped from heavy-gauge steel and finished in a scratch-resistant white powder coat, providing a clean appearance with minimal upkeep. HVAC installers and service techs specify this register when replacing worn or damaged floor grilles in ducted heating and cooling systems.\u003c\/p\u003e\u003cp\u003eThe mffr48w is suited for floor-mounted supply duct terminations in residential homes and light commercial spaces. It installs over a standard rectangular floor duct boot where the finished opening requires a 4 x 8 inch register.
