    Rated 5 out of 5 by Excellant Value! I purchased this 8 months ago and I am very delighted with its quality. The price was ideal and the shipping charge was minute. My purchase arrived sooner then expected, it was easy to install and I am as happy with Build.com as could be! January 22, 2015
    Rated 5 out of 5 by Well made. Replaced a plastic shutter that the sun ate up. This one seems well made and should last a long time. July 7, 2014
    Rated 5 out of 5 by Aluminum Shutter for attic fans Produce was perfect-as ordered. Used to find these in the big box stores, but no more..oh well. At least we can order them online. They work fine..Stay closed when fan is off, keeping heat in & vermin out. Work thru gravity. I have one that's 35 years old, still works great! September 3, 2013
    Rated 5 out of 5 by This damper works great This is the perfect companion for my fan. October 28, 2012
    Rated 4 out of 5 by Not elegant, but it does the job This grille should be extremely durable; its construction is top-notch, with all-aluminum wear points and high-quality weatherstripping. If I were installing it again, I would shim out the bottom to give it a bit of top-in tilt to ensure that the flaps close securely when the fan's not running. Hung plumb, they have a tendency to not shut tightly; this could provide entry for insects. August 7, 2012
    Rated 4 out of 5 by Does the job Easy to install and does the job. August 2, 2012
    Rated 4 out of 5 by good working shutter Fits real well with a Broan 15" attic fan with easy floating shutters from fan power and a nice fitting seal when fan is off. October 6, 2011
    Rated 4 out of 5 by as advertised Performs as expected. Arrived in good condition and was easy to install September 7, 2011

    Broan 433 Shutter

    Is there a mechanical stop to prevent a lower louver to wedge itself under a higher louver by being blown past horizon in high gusty winds, and completely vertical upward? I've been experiencing this with you competitors shutter.
