MASTER GATE SLAVE GATE
Installation of the Closed Position Stops
The Mighty Mule Gate Openers 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
with your dual gate (see Accessory Catalog).
IMPORTANT: 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,
not included) 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 Mighty Mule 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.
