Installation of the Closed Position Stops
The Mighty Mule® Gate Openers fi rmly 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 Mighty Mule® 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 SLAVE 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 SLAVE 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 SLAVE 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.
