The present invention is directed to a wire rope having a blackened finish designed for theatrical productions. The wire rope includes a plurality of strands that have a closed spiral arrangement with each other and are compacted. Each strand includes a center wire spirally surrounded by a plurality of inner wires that are spirally surrounded by a plurality of outer wires so that the outer wires completely encompass the inner wires. The center wire and the inner wires are made from a galvanized material and coated with a lubricant. The outer wires are made from a non-coated steel material. Each strand is compacted so the outer wires create a tight mechanical seal to protect the inner wires. The blackened finish on the wire rope is due to a black oxide coating treatment and provides for low visibility of the wire rope during theatrical performances.
