Linear Arm Gate Openers
Linear arm operators are also known as ram arm openers and linear actuators. All linear arm operators have an external control cabinet. These units are the easiest to install because the linear arm is welded or bolted directly to the gate and post. Linear arms are available in electro- mechanical which is the most popular and hydraulic which can be used for commercial and heavier gates. See layout drawing
