Product Summary

The Lambro® 4in. Aluminum Exhaust Roof Vent Cap with Screen, Damper and Collar is ideal for venting through the roof. The damper seals the vent opening when the bath fan, range hood, and microwave are not running because no exhaust air exits the vent. When the appliance operates, the exhaust air pressure pushes the damper open to let the exhaust air escape from the vent. The vent is for new and replacement installations over an existing 4in. opening. The vent features an opening containing the screen with a net-free area of 10.5 sq. in., allowing for less back pressure. The net-free area of the unrestricted opening is 20 square inches when removing the screen. The vent’s manufacturing material is 22-gauge aluminum for durability and will not rust to maintain longevity.
