Can you please provide the measurements, Specifically how tall the motor is from bottom to top of the motor control lid. Thanks
Reply
The height from the bottom of the motor to the top is 12". That is with the cover door closed. When opening the cover door, the highest point from the bottom of the motor to the top of the cover is 17".
