Exceptionally designed for exterior applications, the SB is easy to install and have large openings to reduce clogging. Standard with flapper damper, it prevents outside air from back-drafting into the house through the dryer. The SB is suited to exhaust fan applications such as dryer, bathroom, or kitchen exhaust venting. The heavy-gauge anodized aluminum construction is corrosion-resistant for durability. Removable from ductwork for easy cleaning for dryer vent use.
No louver manufacturer warrants their louver to prevent water penetration under all possible circumstances of wind and rain.
