How to install an attic gable fan. QuietCool AFG SMT ES 3.0

This gable fan has been well worth the money and effort. I’ve tested it on multiple consecutive days of consistent temperatures. It keeps my attic approximately 8-12 degrees cooler in the summer, which in turn keeps the house cooler.

Comment if you have any questions.
