Product review (1 stars): It appears to be a "knock-off"BEWARE
It was a full 1/8 inch shorter in height than it should have been LxWxH, but was advertised to 'fit' the series overhead oven fan I have.
It was not packaged right, either, it had no Broan logo anywhere on the package or on the product. But I desperately needed something, so I kept it and used it.

Will not look for this at Amazon.com again. I feel cheated.
