MASTER GATE SECOND GATE
The Diamond Gate Operators firmly hold the gates in the closed position using positive
stops. The positive stops help stabilize the gate leaves in the closed position. To further
enhance stability and security, we strongly recommended using an optional GTO
Automatic Gate Lock (see Accessory Catalog) with your dual gate.
IMPORTANT: You need to determine
which side of the driveway you will
mount the control box. From this
point on the gate and gate opener on
the same side as the control box will
be referred to as the MASTER gate
and gate opener. The gate and gate
opener on the opposite side of the
driveway from the control box will be
referred to as the SECOND gate and
gate opener.

Step 1
Attach the horizontal closed position stop plate
to the MASTER gate leaf.
Detach the gate operators from the gates
and move the gates to their closed position
(Illustration A). Using appropriate hardware for
your type of gate (U-bolts for tube or chain link;
screw or bolts for wood or metal) attach the
closed position stop plate (horizontally) about
mid height on the MASTER gate frame. Do not
tighten it completely at this time. Slide the stop
plate toward the frame of the SECOND gate leaf
until they touch (Illustration B). Once you have
moved the stop plate to the correct position,
tighten its hardware completely.
NOTE: The optional ground stop post is used to provide a secure point for the SECOND gate
to close against. If you will be using the GTO/PRO Horizontal Gate Lock accessory with your gate
opener system, the closed position ground stop is REQUIRED, as shown in Steps 2 and 3 on the
next page.
