Large capacity articulating clamp assembly

An articulating clamp assembly for attaching a bracket assembly supporting a traffic control device to an elongate support structure to form a traffic control assembly, the clamp assembly comprising:

• a first clamp member having a first end and a second end, an opening in the first end, an opening in the second end, and an internal channel connecting the openings in the first and second ends forming a substantially straight first conductor path segment therethrough, the first clamp member having a longitudinal axis;
• a second clamp member having a first end and a second end, an opening in the first end, an opening in the second end, and an internal channel connecting the openings in the first and second ends forming a substantially straight second conductor path segment therethrough, the second clamp member having a longitudinal axis;
• wherein the first end of the first clamp member and first end of the second clamp member are connectable to each other to form an articulating joint that connects the first and second conductor path segments to form a conductor path extending through the connected first and second clamp members that is straight when the longitudinal axes of the first and second clamp members are parallel;
• and
• wherein in the assembled clamp assembly the joint is positioned on one side only of the conductor path, wherein the clamp assembly further comprises a bolt for securing the joint in a selected position, and wherein the bolt does not extend across the conductor path.
