A ventilation ducting tool designed for insertion into 4” ducting to prevent cold drafts and debris from flowing into ventilation systems. Built to be embedded in ducts, the backdraft damper is made of sturdy galvanized steel and features two rings of outer rubber gaskets. This enables it to grip your ducting with an airtight seal in either a horizontal or vertical orientation. The butterfly damper blades are made of aluminum and are equipped with a light spring that folds with minimal airflow.
