Ideal for applications with limited hourly cycles, light-duty operators are strong, powerful and highly reliable.


Ideal for increased door weight and frequency of cycles, medium-duty operators make a strong addition to any facility.

What Our Clients Say

Very impressed with The Garage Doctor from start to finish. The technician was right on time, diagnosed the issues immediately, had the parts he needed, made all repairs efficiently, and gave me advice on keeping maintenance of the door. The service price was reasonable. Would highly recommend them for garage door repairs.
