As you can see from below picture: there are 3 parts for the measurements:1,2,3
1.spor 2 is the lowest point of the gate (this spot should be at the same level with the pillar)
2.spot 3 is the net distance between the two pillars. If you want to install the gate on the outside of the pillars, please tell
us in advance, so we can adjust the measurement.
3.spot 1 is the highest point of the gate. Normally it is 30-50cm higher than spot 2.
