The latter are a very convenient and effective design to minimize the costs of time and effort to pass large vehicles in a large entrance target. So, the sliding gates are shifted along the line of fence (fences, fence), which limits the internal space of the parking, and thus save space both in front and directly behind the gate alignment. In addition, such an opening mechanism moves the main canvas on special roller clamps, which make it possible to open a target on any width, depending on the brand of the car. Thus, it will not be necessary to push the entire canvas, if you need to “slip” into a large opening to the usual small car in a large opening.
