INSTALL THE GROUND STOP PLATE
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]. 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 Ground Stop Plates on the inside of the gates.
For Push-to-Open systems, install the Ground Stop Plates on the outside of the gates.
