The Lambro EM-4N is a 4-inch louvred exhaust hood designed for exterior wall termination of residential clothes dryers and ventilation fans. Built from high-quality plastic, this black vent hood provides a long-lasting solution that resists rust and corrosion from outdoor exposure. Its integrated louvres swing open dynamically when exhaust air flows and close firmly when the system stops.
This venting accessory is ideal for homeowners and contractors looking to replace old, cracked, or faded outdoor exhaust caps. The automatic closing louvred design acts as a dependable barrier, keeping birds, insects, and cold outdoor air from entering your duct network. The modern black finish blends exceptionally well with darker siding materials and contemporary architectural finishes.
Ensure that your existing exhaust pipe or flexible ducting has a matching 4-inch diameter for a secure fit. Caulking around the exterior flange during installation is highly recommended to prevent water intrusion into your home's exterior walls. This product offers an affordable and visually appealing solution for finishing your ventilation exhaust setup.
