Position the magnetic lock with armature plate at desired location and tack weld the magnetic lock plate to the gate post.
Do not fully weld or you will burn the wire or lock.

Do not fully weld or you will burn the rubber pieces.
Remove the armature plate with rubber washer and magnetic lock from the junction box and
fully weld the plates.
After it cools-off, reassemble magnetic lock and armature with the rubber washer.
HANDLING:
The magnetic lock, junction box and
magnet plate are ruggedly constructed and designed to
provide years of trouble-free service. Care must be taken,
however, during installation and during actual use so that
the magnet face and magnet plate face are free of dirt,
rust, burrs, paint, or any other obstruction which may
interfere with the magnet and magnet plate making good
contact.

It is necessary to separate the MG 1300
parts from the armature and magnet
plates prior to welding.
Failure to do so will cause the wiring
and rubber pieces to burn and melt.
