The FlexFlow™ elbow maximizes airflow by economically forming any brand and any size of commercial or residential flexible duct into a highly efficient 90 deg elbow. Simply strap the one size fits all FlexFlow™ elbow over the outer jacket of the flexible duct. It's fast, easy and dramatically less expensive than galvanized elbow installations. Adjustable bands allow the FlexFlow™ elbow to fit any size and any brand of flexible duct from 6 to 16 in.
