Medium-Duty Jackshaft Operator With Floor Level Disconnect
14 CYCLES/HOUR 50 CYCLES/DAY
APPLICATIONS
The Opera-MJ is a medium-duty operator
designed for use on standard, high and vertical lift sectional doors or rolling doors(1) and grilles.
The operator can be wall, hood, or shelf mounted on either side of the door. It incorporates a floor level disconnect mechanism for manual operation.
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).
