Model GH

New! Gearhead Hoist Operator- Logic 5.0

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.

CONNECTIVITY:

• 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.
