LAMBRO 1471W-2P 4-Inch Wall Exhaust Vent with Removable Damper

Lambro 1471W-2P 4-In. Plastic Wall Exhaust Dryer or Air Intake Hood Vent with Spring-Controlled Damper, Water-Drip Edge, Flange, 2.4-In. Collar, #1471W-2P

The LAMBRO 1471W-2P is a pro-grade 4-inch wall exhaust vent designed to support maximum airflow in exhaust and fresh air intake installations. Its non-screened opening provides a 14-square-inch net-free area, making it suitable for clothes dryer exhaust, exhaust fans, or fresh air intake applications. The removable damper also supports new and replacement vent installations where duct cleaning access is important.

Built for rain-screen applications, the extended base accommodates the gap between sheathing and cladding. The 2-piece design helps prevent leaks at the joints, while the 1-piece molded base enhances water protection. An improved 0.75-inch drip edge helps direct water away from the vent, and the oversized flange is designed to support a watertight fit during installation.

The vent includes a 2.4-inch collar for through-the-wall installation and a spring-controlled damper that helps prevent outside elements from entering when the vent is not in use. The removable hood facilitates duct cleaning while helping preserve building-envelope integrity. Made from polymer resin with a UV inhibitor, the vent is designed to help resist premature fading.

The plastic vent can be painted when properly prepared, with plastic paint recommended. Installation screws are not included.
