MECHANICAL INTERLOCK
Mechanical Interlock
The ProLine and ProLine G2 Mechanical Interlock can be actuated
by any ProLine or ProLine G2 solid or disconnect door in a multiple-
bay enclosure system. Up to ten doors, including window doors, can
be interlocked. The interlock device engages the door at the center
to provide maximum security. The master door can be positioned in
any location. Only after the master door is opened can slave doors
be opened. The interlock system is modular and easy to assemble;
no drilling or layout work is required to install. Brackets, rods and
fasteners are heavy gauge steel. Meets interlocking requirements
established by General Motors, Ford and Chrysler.
Front-to-Back Interlock
The Front-to-Back Interlock is used to interlock the rear doors of
an enclosure in conjunction with a Master Door Actuator Kit and a
Slave Door Kit. When the Master Door Actuator Kit on the front of
the enclosure is activated (by a solid or disconnect master door)
and the Front-to-Back Kit linkage is in place, the pivot bracket is
pulled, which activates the Slave Door Kit to interlock the back doors
of the enclosure with the front doors.
