The motor worked exactly as expected. Because I didn't purchase the 12" louver from ACF Greenhouses, I had to manually drill a hole to attach the motor. I would have been a lot easier to purchase the louver and motor together - knowing that they're compatible out-of-the-box.

Easy to install and it works great, I’ve had one for over a year now and zero problems.

I used one for one year so far, it is hooked up to a thermostat along with a shuttered exhaust fan. It works perfectly.

Easy to order. Easy to install. Works effortlessly.

I can highly recommend this product.

The exhaust fans were fine. However, the motor for the intake shutters did not seem to match. First, the motor box said it was a Dayton motor. It wasn't. Then, the motor has two mounting bolts, but the shutter was drilled for only one. We had to alter the shutter and drill another hole to make the motor fit. Third, the attachment from the motor to the shutter was not right. It bound on the motor and the shutter. We had to alter it as well to make it work. Installing the first motor took over 3 hours before I got it to work properly.

ACF Greenhouses: I’m sorry to hear you had so much trouble installing the shutter motor. It sounds like you did not receive the installation instructions we provide at https://www.acfgreenhouses.com/shared/files/D8011-Shutter-Ins.pdf . There should have been a copy in a red envelope with your order. It would have saved you a lot of installation time. These motors are made for the Dayton brand shutters, but they work with many different ones that have slightly different installs depending on the shutter size and style. That is why we provide additional instructions to make assembly easier for the customer.
