The Lambro white plastic hood clothes dryer exhaust vent kit featuring 4 In. x 8 Ft. foil flex is ideal for venting through the wall. This kit is used for clothes dryer exhaust and other general venting applications that require moist air and humidity from exiting the home. The hood allows for maximum airflow while reducing back flow of exhaust air. The built in damper prevents back drafts while the removable guard prevents critters from entering the home through the vent. The plastic vent has a UV additive to prevent premature fading due to the sun.
