Tailor your range hood to a taller ceiling with the Windster RA-77 Series Extension Duct Cover. The Windster RA-77 series range hoods come equipped with a duct cover for average-sized 8- to 9-foot tall ceilings. This set lets you couple the range hood with a ceiling between 9- and 10.5feet in height, keeping the intake port at an ideal 28- to 32-inches above the cooking surface. Thick, durable stainless steel is used to craft the piece, featuring smooth edges and seamless design. The duct cover has been approved for use by the CSA for use in both US and Canadian homes.
