I purchased these shutters to go with a Broan 35316 gable fan. When I went to install it, I thought the contractor had not made his opening square, but when I checked it's actually the shutter that's out of square by about 1/4 of an inch on the diagnols. That's not even good by rough carpentry standards for that size hole. I was also surprised at the big gaps in the miters, which continue through the frame. This means that water that drips off the shutters could flow back into the attic. It's possible to seal this with caulk, but not easily since it can't interfere with shutter operation. Even though I've already purchased this and installed it, I'm considering replacing it if I could be sure the replacement unit was of better quality. I would give this a zero rating if I could.

It's white which matches my house color

Cheap, flimsy, out of square, isn't weather tight
