Jack Shaft Operators integrate with the overhead door shaft taking a mechanical advantage of the circumference of the cable drum. For example, an eight foot door lift requirement can be achieved with a horizontally or vertically mounted 36 inch stroke Jack Shaft Operator. The smaller footprint of the JSOs not only saves space but reduces the cost per opener significantly.
