Designed for exterior applications, the SWV 150 6" exterior wall cap is easy to install and has large openings to reduce clogging. Standard with a flapper damper, it prevents outside air from back-drafting into the house through the dryer, bathroom, or kitchen exhaust fan.

The heavy-gauge Stainless Steel construction is corrosion-resistant for years of service. Removable from ductwork for easy cleaning for dryer vent use.
