Gate Bracket Installation

1 If required, install an angle (2" x 2" x ¼" by others) horizontally on the gate, at the same height
as the top surface of the control arm extension.
2 Adjust the eccentric stop as shown so that the wide area of the eccentric is against the arm.
Be sure that the control arm and actuator are in a straight line. Install the gate bracket at the
appropriate point on the gate (or angle, if used).
As an alternative on the Model SW470 only, (2) 3/8 – 16 bolts and a nut plate are provided.
Adjust arm length and then rotate the eccentric stop 180 degrees so that the small thickness is
against the arm. This will provide the necessary deflection in the arm assembly to lock the
gate.
