Dayton Ceiling Shutter Motor Pack 24N066

I Purchased this as a replacement for whole house attic shutter actuator. The old one was buzzing and was a constant noise above the fan noise horizontal whole house ventilator, so it was really pretty loud. I called the manufacturer and ask them what replaces my current model... they recommended this actuator model and suggested I shop around for prices there's was a bit expensive. Zoro had an excellent price with great delivery. Installation was basically to remove and replace with a small difference in the wiring. Net result was absolutely no buzzing and works perfectly! I would absolutely recommend this to anyone that has an old or buzzing attic power shutter vent. [This review was collected as part of a promotion.]
