Review on 🔀 Upgraded Broan 433 Automatic Shutter for Enhanced 353 and 35316 Gable Mount Attic Ventilator with Smart S.E.O Features by Justin Puranik

My 8 year old house was built with plastic slats on the ends of the gable. I live in sunny Florida so having thermostatically controlled forced ventilation is very important. The plastic shutters were falling apart and I needed a better replacement. Broan 433 are close to hole size. I received the package today and am very happy with the aluminum blinds. The blades work independently and smoothly. The units appear to be well built. I'll be installing the blinds this weekend and expect them to be a better service than the original plastic units and I doubt I'll have to do the job again.
