Broan-Nutone 6 In. Mill Finish Aluminum Wall Vent Cap

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.). This cap provides reliable ventilation and features both a back draft damper and welded bird screen, preventing outside air from entering the home or birds and small pests from entering duct work. The back draft damper is spring loaded and features a padded damper zone, which reduces noise from wind induced chatter.

• Not suitable for dryer venting
• Wall cap is made of 22 gauge CRCQ steel construction with a .025 natural aluminum finish for durability and long life
