The Lambro 4 inch aluminum exhaust roof vent is ideal for venting through the roof. This vent is used for bath fan exhaust, range hood exhaust and other general venting applications that require moist air and humidity from exiting the home. The damper allows for maximum airflow while reducing back flow of exhaust air while the installed screen keeps out the outside elements. The vent is made of 22 gauge aluminum. Check local building codes prior to installation.
NOTE: This item can be used as a replacement for Item # 636AL formerly
supplied by Broan Nutone.
