Great Upgrade for Whole House Fan
By Steven Seidenberg
When I purchased a whole house fan from Home Depot 10 years ago it came with plastic louvers that made a lot of noise when the fan was in use. They finally fell apart and I purchased these and to my surprise they are all metal, a great improvement. When using the fan now, it is much quieter because the louvers do not rattle. The shutters came complete with instructions and screws. The only reason I gave it 4 stars instead of 5 is the screws it came with are flat head and not Philips. Highly recommend this product.
