Sterling SWV 100 6" Bathroom Fan Cap
Designed for exterior applications, the SWV 100 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.
