Example of an installation on a chain link fence:
IMPORTANT: To achieve the most efficient
leverage for the gate opener and ensure long
trouble free service, the gate opener needs to
be installed within the following parameters.
The diagram at left shows the optimum
position for gate opener arm in relation to
the gate in the open and closed positions.
Be sure the position of the gate opener and
brackets allows for 1" of clearance between
the gate and the opener in both the open and
closed position, at the same time maintaining
a maximum distance of 13" from the end of the
retracted opener arm to the gate bracket with
the gate in the closed position.
