Mighty Mule FM402 Installation Instructions
11
Install the Closed Position Stop Plates
The closed position stop plate is attached to the FIRST gate to help stabilize the gate leaf in the closed position. An
optional low profile ground stop, when used with the closed position stop plate, provides a secure point for the SECOND
gate to close against.
To further enhance the stability and security of your gate, install a Mighty Mule Automatic Gate Lock [FM143] page 26).If
you will be using the Mighty Mule Gate Lock with your gate opener system, the closed position ground stop is
required
.
For
Pull-to-Open
systems, install the closed position stop plates on the
inside
of the gates
.
For
Push-to-Open
systems, install the closed position stop plates on the
outside
of the gates.
Step 1
Detach the gate opener arms from the gates and move the gates to the
closed position.
Step 2
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 FIRST 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. Once you have moved
the stop plate to the correct position, tighten its hardware completely.
Step 3
The low profile ground stop may be made
of metal or concrete and should be firmly
secured in the ground. The low profile ground
stop should be installed beneath the SECOND
gate, positioned near the leading edge.
