The Broan-NuTone® 641 Aluminum Wall Cap is a robust, easy-to-install vent for exhaust fans (bathroom, range hood, rec room, home gym, etc.).

The back draft damper is spring loaded and features a padded damper zone, which reduce noise from wind induced chatter. Compatible with 6" ducting. Not suitable for dryer venting.
