Broan-Nutone Wall Vent Cap, 6 In., Mill Finish Aluminum, Wall-Mount, Back Draft Damper, Bird Screen

Keeps outside air out and helps your exhaust run the way it should.

A simple wall cap that handles the job without fuss.

Product Overview:

When a vent opening sits on an outside wall, you notice the little annoyances fast. This wall vent cap gives your exhaust fan a clean way out and helps keep the rest in check. It fits the kind of everyday spaces people actually use, like a bath, range hood, rec room, or home gym. The aluminum body brings a plain, steady look, and the built in damper and bird screen do their part without making a fuss. Set it in place and you get a neater finish outside, a softer sound when wind kicks up, and a bit more peace indoors.

Key Features:

• Back Draft Damper: The spring loaded damper helps stop outside air from sneaking back in, so your duct stays more settled.
• Bird Screen: The welded screen gives birds and small pests a firm no, which saves you from nasty surprises later.
• Noise Control: The padded damper zone cuts down on wind chatter, so you hear less rattle and more quiet.
• Easy Install Fit: Made for wall mounting, it keeps the install straightforward and helps the outside opening look tidy.
• Aluminum Build: The mill finish aluminum gives you a solid, practical surface that feels made for real weather, not just a showroom.
