Lambro 3.25 x 10in. 22 ga. Aluminum Wall Exhaust Hood Vent with Spring Gasketed Damper and 5 in. Tail

The Lambro 3.25-in. x 10-in. Aluminum Exhaust Hood Vent with 5-in. tail is ideal for venting through the wall. It features a spring-controlled opening and closing gasketed damper that prevents outside elements and air from entering the vent. The damper seals the vent opening when the kitchen, 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 exhaust vent can easily be used for new and replacement installations over an existing 3.25-in. x 10-in.opening. The vent's manufacturing material is 22-gauge aluminum for durability and will not rust to maintain longevity. Please be sure to check local building codes before installation.
