The bellmouth inlet is transitioned to fit a rectangular duct where the vertical height is insufficient to accommodate the standard bellmouth size. The inlet at the top and bottom of the bellmouth is bent to match the restricted clearance of the rectangular duct. The assembly provides a smooth airflow transition from the rectangular duct into the round or spiral duct system.
