Step 2
Swing the gate to the desired
opening position (70 - 120 degrees)
and make the second mark “S2” on
the ground.
Step 3
Measure the distance “Z”, between
“S1” & “S2” in mm, then using “Z”,
look up gate opening Angle and
dimension C for size of Drive Arm
supplied (see Table 5).

Say “Z” is measured as
1482mm, then the closest
Z value in table = 1486mm.
Dimension “C” for a 400mm
Drive Arm is therefore
538mm.
