    Installation Overview Pull-to-Open Gates (Gate Opens into the Property) The diagram shown below is an example of a pull-to-open installation on a chain link fence and dual gate.

    The position of the post bracket determines the leverage and efficiency of the opener. The post bracket position also sets the clearance between the opener and gate in the open and closed positions (minimum 2 inches for safety reasons). The curved design of the post bracket works well for installations on round and square fence posts. Because the post bracket carries the entire thrust of the active opener, bolts that completely penetrate the fence post must be used.
