3-1/4" x 10" Aluminum Wall Cap

Note: Size shown indicates the Duct Size of this product. The Lambro 3-1/4 inch x 10 inch aluminum exhaust vent is ideal for venting through the wall. This vent is used for bath fan exhaust, range hood exhaust, microwave 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 spring controlled damper. The vent is made of 22 gauge aluminum and has a foam gasket installed to provide a tight seal and ensure quiet operation. The built in spring loaded damper prevents back drafts while preventing critters from entering the home through the vent when not in use.  Check local building codes prior to installation.
