Step 1
Find the center between the two roller/gate support posts. This should coincide with the position of the
center point of the operator.
Dig a hole deep enough for the post mount adapter installation.
The required post mount adapter depth is dependent on soil conditions and local code (please check
your local code).
Figs A and B show where to locate the post mount adapter in relation to the string and gate support
posts. Be sure that you have a minimum of 7” from the string to the ground.
It is crucial that the top of the post mount adapter is level and exactly 3” below the string.
