Measuring and Marking for the Gate Bracket
Before proceeding, begin with the gate in the fully closed position. There are two methods described to determine
proper location of the post brackets:
• Paper template (to be cut out) located on the back page of this manual.
• Tape measure.
Either method will work depending on preference.
NOTE: Be sure gate is in closed position before proceeding.
