## Description

The Lambro White Plastic Single-Flap Bath Fan Exhaust Vent Kit featuring a 4-in. x 8-ft. UL 181 flexible air connector is ideal for venting through the wall. This kit is used for bath fan exhaust and other general venting applications that require moist air and humidity to exit the home. The single flap allows for maximum airflow while reducing back flow of exhaust air. The vent can be painted to match your home’s trim color. Make sure to check local building codes before installation.

• Single flap allows for maximum airflow while reducing back flow
• UV inhibitor helps prevent premature fading of vent
• Paintable to match your home’s decor
