Review on 🌬️ Efficient Ventline (V2111-11) Colonial White Horizontal Exterior Wall Vent for Optimal Airflow by Muhamed Hogan

That's a piece of crap. There was plastic everywhere. The central support broke. Not worth going back, but if you can find a brand other than Ventline that fits I'd say go for it. These parts have been in production for almost 15 years and I think the mold tooling is also 15 years old and should be replaced, but Ventline clearly has no quality standards and they don't care about the quality of their products.
