Liftmaster J331L5 Industrial-Duty Jackshaft Operator 1/3 HP

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.


MyQ Technology enables you to securely monitor and control your facility operator and lights with your smartphone, tablet or computer for greater peace of mind.

Alerts can be received as email or pop-up (push) notifications on a mobile device, ensuring the status of your commercial door.

MyQ Mobile App is a free download with no annual activation fee.

Safety and Security

Security+ 2.0™ safeguards your facility – with every click, a new code is sent to the commercial door operator so the door opens only for you.

UL 325 requires all commercial door operators to be either constant pressure to close or be equipped with a primary external monitored entrapment protection device.
