Swing Arm Gate Openers
Swing arm gate openers are available with a top or bottom mounted arm. The top mounted arm units generally are larger, have a very heavy chassis, and large oil soaked gear reduction boxes. They are very durable and are great for heavy usage. The bottom arm style such as the Doorking 6100 are aesthetically pleasing because the arm located at the bottom of the gate is not noticeable. The bottom arm units are constructed less robustly than their heavier counterparts, but have a similar life span. See layout drawing
