Often referred to as man gates or walk gates, a single leaf chain link fence gate has one gate leaf. Normal widths of single leaf gates are 3′,4′ and 5, wide. However, single leaf gates if built correctly can cover spans of up tp 20.
In residential applications they are used for pedestrian access, or in areas where there isn’t enough room for a double gate. Most anything a homeowner would want to fit into the backyard will fit through a single gate of 5′ wide.
