These Uriah Products splice connectors are quick and easy to install. Just run both wires through the connector, fold the top over the metal insert and the wires, and squeeze the connector with some pliers to lock everything into place. The metal insert will do most of the work and cut through the insulation to make the connection between wires. These one accommodate 14 to 18 gauge wire and come in a pack of six. | Uriah Splice Connector Kit
