This white 4-inch louvered vent cover works as an exterior exhaust outlet for dryers and bathroom fans. It also works as an indoor air supply vent. It can be installed on house walls, garage walls, shed siding or apartment exteriors, and it can replace a worn, rusted or broken vent cap.
The body is thickened PP plastic. It resists UV fading, impact cracking and outdoor moisture. Three self-operating louvers swing open under exhaust airflow and close when the dryer or fan shuts off. Closed, they block rain, snow, cold drafts, leaves and pests.
A detachable aluminum alloy mesh grille helps keep out mosquitoes, bugs, small animals and lint. It removes without tools, so you can rinse off dirt and lint. The inner opening fits standard 4-inch duct, and the larger outer frame covers uneven wall cutouts. To install, cut a matching opening in the exterior wall and connect the vent to the duct with hose clamps. Then fasten the frame to the wall through the pre-punched holes with the included mounting screws.
