STEP 1
POSITION THE BRACKETS
If this operator is a replacement for a Miracle-One™ operator, use the
existing post bracket and gate bracket. Remove the Miracle-One™
operator from the brackets and proceed to the next step.
If your application is Push-to-Open, refer to the illustrations in the
Appendix.
The measurements shown below are typical for a standard installation.
Your installation may be different. The gate bracket MUST be installed in
an area that can withstand heavy forces. Additional reinforcement steel
plates may be necessary for mounting.
1. Close the gate.
2. Choose a vertical mounting location for the post bracket.
3. Place a measuring tape under the center of the gate hinge point and
measure out dimension
A
(see chart).
4. Use a screwdriver or dowel rod to temporarily mark the location of
the first measurement (Figure 1).
5. Measure out dimension
B
(see chart) from the previous mark. Use a
screwdriver to mark the location of the second measurement
(Figure 1).
6. Align the post bracket as close as possible above the screwdriver or
dowel rod and tack weld the post bracket in the desired vertical
position.
7. Position a level on the post bracket and measure 35-1/2 inches (90.2
cm) over from the center hole of the post bracket and mark the
location on the gate (Figure 2).
8. Measure 2-1/4 inches (6.4 cm) down from the previous mark and
center the bracket on this mark (Figure 3). Tack weld the gate bracket
in this position.
NOTES:
•
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 (Figure 1). If the
distance is greater than 4" (10.2 cm) entrapment protection for this
area is required.
•
While the gate is in the fully open position, the operator needs a
clearance of 11-1/4" (28.6 cm) as shown (Figure 2).

NOTE:
The ideal installation measurements are A = 7-3/4" (19.7 cm) and
B = 8-1/2" (21.6 cm). If different measurements are used, the sum of A
and B cannot be greater than 18" (45.7 cm).
