Lambro 4 in. 26-Gauge Galvanized Steel Wall Exhaust Hood Dryer Vent with Damper and 11 in. Pipe

The Lambro 4 in. 26-Gauge Galvanized Steel Wall Exhaust Hood Dryer Vent with Damper and 11 in. Pipe is ideal for venting through the wall. The damper seals the vent opening when the clothes dryer or bath fan is 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 is for new and replacement installations over an existing 4 in. opening. It features an opening with a net-free area of 20.5 sq. in. allowing for less back pressure. The vent's manufacturing material is 26-gauge galvanized steel for durability and longevity. Make sure to check local building codes before installation.

• Heavy gauge for durability and longevity
