Black ABS Plastic Roof Exhaust Vent – Damper – 1/4 inch Removable Screen – 4 inch Snap-In Collar – Item #3540RCS

Our products are Made in the USA

A gravity damper and removable 1/4-inch screen in the 4-inch roof exhaust vent prevent outside elements and air from entering the vent when not in use. The damper opens and allows the exhaust air to exit the vent through the sufficient opening containing the screen, which has a net-free area of 12 square inches. When the screen is removed, the net-free area increases to 16 square inches, allowing for maximum airflow.

Dryer Vent

The Lambro 4-inch black ABS plastic exhaust vent is perfect for roof venting.

It includes a gravity damper and a removable 1/4-inch screen (REMOVE THE SCREEN FOR CLOTHES DRYER APPLICATIONS) that stops outside air and elements from entering the vent. The damper closes the vent when the clothes dryer or bath fan is off, as there is no exhaust air leaving the vent. The raised channel on three sides of the damper ensures it remains closed during windy conditions when the appliance is not in operation. When the clothes dryer or bath fan is in use, the exhaust air pressure forces the damper open, allowing the exhaust air to exit the vent.

WARNING:The roof vent applications consist only of shingled roof installations.

The exhaust vent is for new and replacement installations. The vent frame comes with six predrilled nail holes to secure the vent to the roof. When using the vent to exhaust a clothes dryer, check the inside of the vent regularly to prevent lint build-up.

The vent’s manufacturing material is ABS (Acrylonitrile Butadiene Styrene) with a UV additive to prevent premature fading caused by sunlight. It would be best to prep the vent before painting it; we recommend plastic paint to paint the plastic vent effectively.

Make sure to check local building codes before installation.
