With a slide gate, the actual gate itself is stored against the rest of the perimeter fence, thus better protecting the gate when it’s opened. This design also helps when there is snow on the ground. Swing gates have a complete 90 degrees to travel through the snow while slide gates have a straight line in which to travel. This alleviates undue stress on the gate. These gates work best on property that is flat and do require a lot of horizontal space to operate.
