Dual Gate Installation
Turn power switch OFF on the bottom of the control box. Disconnect gate openers by removing hairpin clip
and clevis pin from the gate bracket end of the openers. Disconnecting the openers will allow the gates to
swing freely during installation of the gate lock.
NOTE:
In a DUAL GATE INSTALLATION the gate opener on the same side of the driveway as the control box
is known as the PRIMARY GATE OPENER and that gate is referred to as the PRIMARY GATE. Conversely the
gate opener on the other gate is referred to as the SECONDARY GATE OPENER and the gate is referred to as
the SECONDARY GATE.
IMPORTANT:
To use the gate lock on a dual gate system, the gate sequencing must be set so the PRIMARY
GATE opens first and closes last, and the gate lock has to be mounted on the PRIMARY GATE and the
lock receiver is mounted on the SECONDARY GATE. Some Linear and Mighty Mule gate operators are
preprogrammed with this functionality. The secondary gate requires a positive stop. If your gates are not
sequenced in a manner that works like this, you'll have to change the sequencing on your gate opener. Follow
the instructions in your gate opener installation manual for programming dual gate sequencing.
Step 1: With the gate in the closed position, determine the best location for the lock and lock receiver. The
lock and receiver must be level and aligned with the opener. Also, the lock should have a solid
surface or cross member to provide stability (see illustration below).
Step 2: Clamp receiver and lock together (with receiver pin hole and lock slot aligned) to the gates, mark
their positions to drill holes. The receiver must be mounted on the SECONDARY GATE with
carriage bolts, not U-bolts, to allow lock to seat properly.
Step 3: Recheck the lock’s position and alignment. Hold latch open with key and operate gate. Drill the
holes on gate supports through the slots in the lock bracket. U-bolts and saddles can be used to
mount the lock on chain link gate supports. Secure the lock to the PRIMARY GATE. Install clevis
pin and locking cap by placing clevis pin through slots in lock receiver and hammering the clevis
pin into the locking cap, secure the lock bracket and check the alignment again.
Lock and receiver must be level and aligned with opener.
Hold latch open with key to operate gate.
Receiver pin hole and lock slot must line up.
