Imperial 3"-4" x 5' Bath Fan Vent Kit

This convenient Imperial Bath Fan Wall Vent Kit is ideal for bathroom fan venting applications that require through-the-wall installation. Designed for use with 3-in or 4-in bathroom fans, the kit includes an optional increaser to adapt a 3-in fan to 4-in duct when required. The low-profile vent hood is constructed of UV-resistant plastic that resists fading and discoloration from the sun, and can be painted to match the exterior of your home. Its louvers open easily for maximum airflow, and close when not in use to help prevent back drafts. For safe and efficient operation, the kit features a 4-in x 5-ft flexible vinyl duct. Designed for easy installation, the kit also includes two adjustable plastic clamps and a 4-in mounting collar.
