About This Product

Add our automatic shutter to finish your install of standard, solar, and premium series Maxx Air gable mount ventilators in your home if you are not installing behind existing louvers. Each aluminum louver is individually padded with felt for an extremely quiet operation. No special tools are required for installation and the frame has pre-punched holes to secure it in your attic space with zero hassle. This exterior shutter automatically opens and closes when the attic fan turns on and off and helps to shield your attic space from the elements when the gable fan is not in use.

        Q:The answer to a question says the back of the louver is 15" round in the back. How far in the back of the louver does the louver extend?
        by|May 19, 2023
        2 Answers
        Answer This Question

        A:  Tech support’s answer “it doesn’t extend very far at all” is not an answer to “how far back does it extend. Why did you even bother to answer?

        by|Jan 15, 2024

          A:  The louver does not extend in the back far at all.

            No issues - clean industrial look - installed easily - opened up 15" ID to 17" to accommodate fan housing diameter - opens and closes allowing plenty of air flow - gravity closes louvers every time - would purchase again - no issues.

            WELL MADE EXCEPT
            Well made except the plastic pins which the louvers rotate on. Wondering how long they will last.Time will tell.

              Good solid frame. Lightweight louvres are easy to bend through. Clean thoroughly if you’re going to paint it!

              Pro: The product is well made and functions as it should. Con: The one problem is in regards to the info on this product. It is even incorrect on the box. The web page and the box state that the rough opening is 18 in. x 18 in. The actual measurement of this unit is 18.125 which means the rough opening should be 18.375 in. I made the rough opening for it, based on the info on the web page, before I received it. I was very irritated when I went to put the unit in and it didn't fit, which meant more work in a hot attic, to increase the size of the rough opening.
