Artistic Wire large crimp Connectors are the perfect cold connection to join large gauges of Artistic Wire together. Perfectly calibrated for 12, 14, and 16 gauge wires. To use place one end of the wire that you are joining half way into the crimp connector. Place the other wire in the opposite end so that the wire meet in the middle. Use the back notch of the mighty Crimping pliers for the 12 and 14 gauge wires and the standard crimp pliers for the 16 gauge wires gently squeeze one side of the crimp then the other for a secure connection.
