The EZ-Flow balancing damper is designed to balance airflow and eliminate hot and cold spots. According to the manufacturer, the unit is ideal for applications where airflow adjustments are needed with no means of installing a conventional balancing damper. Designed to be installed in the boot collar, the damper’s installation is made from the boot outlet by hooking the mounting plate hook onto the collar. It is then secured by using one sheet metal screw. The damper can be adjusted by pulling the 90-degree metal bracket for proper cfm. No tools are needed for adjustments.
