The LAMBRO 481UL bathroom venting kit provides a comprehensive solution for efficient and reliable exhaust fan installation. Designed specifically for bathroom ventilation, this kit includes a 4-inch white plastic single flap vent that prevents outside elements from entering when the fan is not in use, ensuring a clean and dry bathroom environment. The kit also features a 4-inch by 11-inch aluminum snap-lock tail pipe for secure attachment to the vent, along with a 4-inch by 8-foot flexible UL 181 Class 1 air connector that facilitates easy routing through tight spaces. An optional 3-inch to 4-inch plastic increaser allows for versatile fitting options, and two metal spring clamps secure the connections firmly for optimal performance. The foil flex duct's maximum operating temperature is 250°F, making it suitable for typical bathroom exhaust applications. UV inhibitors are incorporated into the duct material to help prevent premature fading and deterioration over time, extending the longevity of the vent system. This kit is not intended for clothes dryer venting and is specifically engineered to meet the demands of bathroom exhaust systems, providing a durable, corrosion-resistant, and easy-to-install solution for maintaining proper ventilation in residential settings.
