Lambro 289W Dryer Vent Seal

The Lambro 4- In. exhaust wall vent features a floating damper that prevents outside elements and air from entering the vent. The floating damper seals the vent opening when the clothes dryer or bath fan is not running because no exhaust air exits the vent. When the clothes dryer or bath fan operates, the exhaust air pressure pushes the floating damper to let the exhaust air escape from the vent.You can easily use the exhaust vent for new and replacement installations over an existing 4- In. vent pipe. The vent frame comes with four screw holes to secure the vent and a caulk-friendly frame for completing the installation. The vent features an opening and closing cover that enables easy inspection and cleaning. Make sure to check the inside of the vent regularly to prevent lint build-up when using the vent to exhaust a clothes dryer.The vents manufacturing material is high-impact polystyrene (HIPS) with a UV additive to prevent premature fading caused by sunlight. You need to prep the vent before painting; plastic paint is recommended for effectively painting the plastic vent.Make sure to check local building codes before installation.
