Whole House Fan Shutter Replacements

Tuesday, August 30, 2011

After looking for awhile for replacement shutters for our whole house fan, I came across these from Dayton. I was a bit skeptical, as they were about 60% of the cost of others I'd seen. I took a chance and ordered them. They arrived, the fit was perfect, installation was a breeze, and I no longer have a 3'x3' hole in my ceiling! And to boot, my order arrived two days sooner than expected! Priority delivery for standard shipping!

Perfect fit, inexpensive, lightweight.

Directions were a bit vague regarding the connection between the spring and shutters. Easily figured out.

This shutter well made and much better designed than the typical injection molded plastic frame units. A wonderful product at a good price.
