INSTALLATION STEP 2 DETERMINE MOUNTING LOCATION MEASURING AND MARKING FOR THE GATE BRACKET Before proceeding, begin with the gate in the fully closed position. There are two methods for determining the proper location of the post brackets: • Paper template (Located on the back page of this manual. Must be cut out.) • Tape measure. Either method will work depending on preference. NOTE: There should only be a maximum of 4" (10.2 cm) from the center of the hinge to the edge of the post or column. If the distance is greater than 4" (10.2 cm) entrapment protection for this area is required. TEMPLATE METHOD 1. Close the gate. 2. Place the template (provided on the back page of this manual) under the center of the gate hinge point. 3. Use a screwdriver or dowel rod to temporarily mark the location in front of the gate post. TEMPLATE METHOD TOP VIEW Gate Hinge Point Gate Post Gate 4" (10.2 cm) maximum OR TAPE MEASURE METHOD 1. Close the gate. 2. Place the measuring tape under the center of the gate hinge point and measure out 7 inches (17.8 cm). 3. Use a screwdriver or dowel rod to temporarily mark the location of the first measurement. 4. Measure 7 inches (17.8 cm) from the previous mark. 5. Use the screwdriver or dowel rod to mark the location of the second measurement. ALTERNATE DIMENSIONS The ideal installation measurements are A = 7" (17.8 cm) and B = 7" (17.8 cm). If different measurements are used, the sum of A and B cannot be greater than 15" (38.1 cm).
