Medium-Duty Jackshaft Operator With Hoist
Medium-Duty Jackshaft Operator With Hoist 14 CYCLES/HOUR 50 CYCLES/DAY
Download Product BrochureThe Opera-MH is a medium-duty operator designed for use on standard, high and vertical lift sectional doors or rolling doors and grilles.
The operator can be wall, hood, or shelf mounted on either side of the door. It incorporates the patented Hoist-a-matic®, a self-engaging chain hoist for manual operation, which simplifies operation and installation.
The operator is available with the new Electronic Control Board (BOARD 070) with or without the option of electrical control for MONITORED external entrapment protection devices (UL325-2010 compliant).
