Questions & Answers

Do the louvers operate independently or are they joined with some kind of metal wire device?

Do the louvers operate independently or are they joined with some kind of metal wire device? I'd be using these in an unconventional way, on a porch, is why I ask. I'd love it if the louvers were rigged to all work together so I could manually open and close the vents.
Asked by: studiopop
I think the force of the air generated by the fan blows and holds them open while its on. Then gravity shuts them when it stops.The bottom of the flaps are weighted so they go back to the closed position when no air is blowing on them.

Hello, how big will the CUT OUT hole be for this vent?

Product #433 Broan louver says its 16.75in x 16.75in... i just wanna make sure that when I cut my hole into the side of my house that I dont cut it to big and the louver just falls through the hole. So i need to know the size of the CUT HOLE in order to make sure the the edges can be screwed down. Thanks
Asked by: Jarred
The vent is about 1/2" smaller than the rough-in size, depending on the type of siding you have and whether you intend to put trim around it, the size in the instructions may work for you. If you only want to run a bead of chalk around it when finished, I would go with 16.5"x 16.5". I made my opening prior to receiving the vent, used James Hardie plank siding, and put a small trim piece around the vent and butted the trim to the siding.

Do the louvers go inwards to the attic?

Is this an intake vent and do you have it in a 12"x12" or 14"x14"
Asked by: Ray
Thank you for your questions. The louvers open outwards (to the outside). This is not an intake vent. This would be used with a cable fan that moves air out when in operation. While air is needed inside, this is not the intake. To be sure that your questions are properly answered, I would encourage you to contact our Technical Support Department at 888-336-6151 and speak with them directly. Thank you.

16.75 in. x 16.75 in. Aluminum Automatic Gable Square Mount Louvered Shutter Attic Vent is rated 4.0 out of 5 by 27.
Rated 3 out of 5 by from Installed over attic fan in roof rafters to close when... Installed over attic fan in roof rafters to close when fan is off. Not sized for 16" rafters so added a frame to support it. Another shutter is installed in the ceiling to allow air into the attic. Must be closed in winter as attic is a "conditioned" space and shutters don't seal enough.

It looks good & works well, seals tightly, when the fan is shut down. Does not rattle, when air flows from the static vent, on the lee side of my shed. Looks like a good choice, time will tell ! Yes I would recommend it !

I like the unpainted part I can spray paint it any color I choose. I don't know how long it will last but it being aluminum it should last a long time, especially with it painted.
