The Lambro 7 In. black ABS plastic exhaust roof vent with a molded 1.5 In. removable collar is ideal for venting through the roof. This vent is used for bath fan exhaust, range exhaust and other general venting applications that require moist air and humidity from exiting the home. The exhaust vent allows for maximum exhaust airflow using a damper that prevents back drafts. A preinstalled screen prevents critters from entering the home through the vent when not in use. Made from ABS plastic material for durability and to maintain longevity. Check local building codes prior to installation. WARNING: This roof vent can ONLY be used for shingled roof installations.
