Can I locate the control box further from the gate than the 6 supplied cable allows?
Yes. You must buy new cable(s) as needed up to 40′ long. We do not substitute the original cables. In a double gate application, you could use the supplied 25′ cable as a substitute for the supplied 6′ cable and then purchase a 40′ cable. Keep in mind though that both cables, one from each operator must reach the control box where they each must plug in.
