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 and bathroom exhaust venting. The heavy-gauge anodized aluminum construction is corrosion-resistant for durability. Removable from ductwork for easy cleaning for dryer vent use.
