Gearhead (GH) style commercial door operators employ lubricated gears for heavy industrial, high-cycle applications. GH-style operators include a floor-level chain hoist to ease manual operation in an emergency or power outage.
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.
