Product Description

The Lambro white plastic single flap exhaust vent is ideal for venting through the wall. This kit is used for clothes dryer exhaust, bath fan exhaust and other general venting applications that require moist air and humidity from exiting the home. The single flap allows for maximum airflow while reducing back flow of exhaust air. The vent can be painted to match your home’s trim color.
