T-style trolley commercial door operators are optimal for general industrial applications. Suspended from the ceiling, the operators are used on sectional overhead doors with standard lift. T operators are directly attached to drive and control the door.
Jackshaft (J) style commercial door operators are optimal for industrial applications. Doors used with this operator should be balanced with the ability to be manually lifted by hand in an emergency or power outage.
The operators are typically mounted to the wall when used with smaller sectional overhead doors with a vertical or high lift and mounted to the wall or the front of the hood when used with rolling doors and grilles. J operators are attached to the door jackshaft to indirectly drive the door.
