A. 14" minimum
B. 27"
C. Length of C = E * 40%.
The length of C is 40% of E. Arm should be 90° from gate
when open and straight when closed. Distance from the
center of the gate operator output shaft to the swivel
arm nut. Note: C is the short part of the swivel arm.
D. Length of D = E * 60%.
The length of D is 60% of E. Arm should be 90° from gate
when open and straight when closed. Distance from the
swivel arm nut to the center of the gate bracket.
Note: D is the long part of the swivel arm.
F. If the gate length is less than 10 feet, F should be at
least 1/4 the gate length.
If the gate length is greater than 10 feet, F should be at
least 1/3 the gate length.
For uphill or heavy gates, F should be at least 1/3 gate
length.
Refer to the illustrations below to determine the measurements of the gate operator and concrete
pad.
