    5 Star Review | Best Shutter

    I replaced an old gable vent with this new shutter. Works great and no cold air blow back in the winter.

    Works well

    The Aluminum Gable Shutter works extremely well when you pair it with an attic gable fan. The gable fan pushes air out of the attic through the Shutter and the shutter closes after the fan is off. Since the Shutter is 20" I had to do a minor re-frame for it to fit.
