Attach the rear mounting bracket according to the
dimensions in Figure 4.
WARNING! You must achieve the A and B

necessary to achieve these dimensions (I.e.,
cutting or extending the bracket provided)
If you have a steel gate post, weld the rear bracket
directly to it. If the gate post is made of any other
material, attach the optional mounting plate, with
lag bolts or anchors, and weld the bracket to it.
For an outward swing gate refer to Figure 5.
