Easy as pie. I just screwed the plate on above the door, attached the motor, attached the line to the door, adjusted the raising and lowering height and viola, done! 15 minutes. I put it on a timer that shuts on/off at 6:30 and 6:35 am, and on/off 9:00 and 9:05 pm. If a ninny like me can do this, you can too!
