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 single gate. Mounting the opener on a masonry column requires special procedures; see Column Installation Information on page 34 if you intend to mount the opener on a column. -
Page 15: Installation Of The Mounting Hardware
Installation of Mounting Hardware 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. 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. - Page 16 Determining the Mounting Position of the Post Bracket Assembly and the Gate Bracket Step 3 NOTE: The following steps are 3/8" x 2" Bolt Insert the " x 2" bolt through intended for pull-to-open gate the center hole of the post installations.
- Page 17 Step 6 Study the 4 " x 4 " setback template (see insert) provided with this manual. Once you are familiar with its illustrations, cut and save the template from the insert. The template will determine the correct position of the post pivot bracket before mounting the opener on the fence post.
- Page 18 Installing the Post Bracket Assembly and Gate Bracket Step 7 Mark reference points for bolt holes on the fence post through middle of bracket slots. Marking reference points in this manner allows room for adjustment when mounting the post bracket assembly and gate bracket. After marking your reference points, remove the opener and brackets from the fence and gate.

Questions and answers
Can you install the opener onto a metal post?
Yes, the Mighty Mule opener can be installed on a metal post. In fact, if the fence post is smaller than 6 inches in diameter or 6 inches square, it is recommended to use a metal post instead of wood to ensure stability while the opener is moving the gate.
