The OLC-2 eliminates the need for soldering, crimps, and expensive connectors, all while creating a perfect connection between two wires. The two wires are stripped 5/16″” and then slid into opposing ends of the OLC-2.  A set screw on each side of the OLC-2 is gently tightened.  The OLC-2 can also be used to create perfect connections with Thermocouple wire, which means no more bulky TC connections.
