By providing a single housing, component or element incorporating a plurality of passageways or receiving zones formed therein in cooperating association with a mounting ring or clamp constructed for being quickly and easily secured to a clamp, conductor or conduit mounted to an electrical box, junction box, meter box, or similar enclosure, an efficient, easily manufactured and easily assembled bonding bar or grounding bridge is achieved. Preferably, the plurality of passageways / receiving zones are constructed with each passageway or receiving zone cooperatively associated with a locking screw or set screw configured to enable grounding conductors to be inserted through the passageway / receiving zone and securely mounted therein. In this way, grounding conductors from telephones, cable televisions, satellite receivers, radios, television antennas, and the like may be inserted into the passageways / receiving zones and securely mounted in the desired position.
