## Description

Under eave vent for bathroom fan and dryer venting.

Review: Absolutely perfect - If you’re like me, you’ve read ALL the reviews on similar items and trying to justify buying the more expensive version. I bought these with skepticism thinking it seemed like too good a deal, but they actually are. Perfect product for this application. I used a 4:5” hole saw to cut opening in soffit. This gave just enough clearance to fit hose and clamp through already mounted to vent. I also cut a small piece of ss screen and mounted inside opening for bug protection. Product exceeded expectations and worked perfect for my intended application. HIGHLY RECOMMENDED!
Review: best option I could find, great price - I installed 3 of these. I like that this has a flap that prevents back flow. I also really like that I could put these right at the edge of my soffit, so the warm vent exhaust blows away from the house and rises into the open air, rather than back up the soffit vents. The only other option I could find out there with these features costs about $130. My main complaint is that on very could nights, the flap freezes shut because of some condensation build up. But usually after running the fan for about 10 minutes, the ice melts and the flap opens.

### ⭐⭐⭐⭐ They work, but how long.
*by G***N on January 1, 2023*

Low price and delicate product. If I could find a sturdier product, perhaps metal, I would buy it. The plastic frame can easily be distorted, so tighten the screws carefully. I may try painting them for some uv protection but don't get any on the hinge. I expect this will be the weak point for failure. They are small tabs that will become more fragile with age. The three pieces in photo is all you get, no screen, screws, hose fasteners, or gasket. I used a 4.25 dia hole saw, but advise getting at minimum a 4.5 dia for an easier installation. After securing the flex hose to vent with tie wraps, the tie wrap would barely fit into the 4.25 in hole. After securing the screws so the flapper still rotated easily, I then caulked between vent and soffit to keep bugs out. There is no screen inside these vents to keep out bug if they get past the flapper.
