" 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.
Remove hairpin, clevis pin, and washer from front mount and close the gate. Rest disconnected opener on cross member of
gate. Stand inside property next to fence post and place one end of template over center of gate hinge. Place the other end of
template over the post pivot bracket hole (either of the two mounting holes in post pivot bracket can be used) where the
opener will be attached. Be sure to hold the template at a 90º angle between these two points and measure 4

the center of the gate hinge. You will need to rotate the post pivot bracket or the entire post bracket assembly to align it with
the square angle of the template. THE ANGLE BETWEEN THE GATE HINGE AND THE POST PIVOT BRACKET
MUST MATCH THE ANGLE OF THE SETBACK TEMPLATE.
NOTE: If you move the post pivot bracket, be sure one of the post bracket holes is aligned
with the rest of the assembly (the center hole should already have a bolt through it).
The post pivot bracket can be flipped over to give more position options.
