Product Description
Optimized for shingled roof installations, this Lambro 4-inch black ABS plastic exhaust vent is an effective solution for both new and replacement roofing projects. It features an integrated gravity damper designed with a three-sided raised channel to remain securely closed during windy conditions, preventing outdoor air and elements from entering when the connected appliance is idle. When a dryer or bath fan is active, exhaust pressure forces the damper open to allow air to exit freely, while the removable 1/4-inch screen provides protection that should be removed specifically for clothes dryer applications to prevent lint buildup. The unit is constructed from durable, UV-resistant ABS plastic to resist sun damage and features six pre-drilled nail holes for a secure installation, with the option to customize the finish using plastic-specific paint after proper surface preparation.
