It is important that a sliding gate moves smoothly through its entire opening so good quality wheels with sealed ball bearings running on a straight metal track fixed to a concrete footing should be used. The bottom of the gate should not contact the track for the whole opening of the gate, if it does the automatic operator will NOT work properly.
DO NOT USE THREE WHEELS on a sliding gate as this may de-rail the gate. Two wheels will always bear the load
evenly. If the gate is very heavy then use two larger heavier duty wheels.
If the ground drops off the edge of the driveway a steel rail can be used to support the gate track. This rail should be
in line with the driveway so if the driveway slopes up a bit so should the steel rail.
