Bath Fan Exhaust Through-Wall Vent Kit

The Lambro 4 inch x 8 foot Single Flap Bath Fan Exhaust Through-Wall Vent Kit is designed for exhaust fan installations in bathrooms. It includes a white plastic single flap vent, a 4 inch x 11 inch aluminum snap lock tail pipe, an 8 foot length flexible UL 181 Class 1 air connector, and a 3 inch to 4 inch plastic increaser. The kit also comes with two 4 inch metal spring clamps. The single flap allows for maximum airflow while preventing backflow of exhaust air and outside elements from entering the vent. The vent can be painted to match the home's trim color. This kit is suitable for venting moist air and humidity from the home and can be used for both new installations and replacements.
