Grilles are the vents through which air is pulled out of a room for circulation back to the central heating or cooling unit. Grilles do not have the damper controls found on registers. Imperial Sidewall Grilles are installed in cold air return ducts. They provide return air circulation within a room, where unobstructed flow is required for heating/cooling system efficiency. Available in a wide range of sizes, these painted grilles have a durable powder-coat finish and are one piece all-steel construction with 1/3" spaced fins set at 20° angle and a 3/16" margin turnback. For size selection, measure the air duct opening.
