LiftMaster J - Elite Commercial Door Hoist Operator (Logic 5.0)
Medium Duty Door Jackshaft 1/2HP Operator
Starting at: $679.00
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.
