Last week Ideal announced their new solution for butt splicing wires together quickly and easily: SpliceLine in-line wire connectors. They tout two major uses for the new connectors, making prefabbed electrical assemblies faster to install and lengthening short wires inside of electrical boxes.
To use the connectors you simply push the end of a stripped wire into the connector — no crimping or twisting. The connectors are small enough that three can pass through a 1/2″ knockout, and they accept 12-20AWG solid and 12-16AWG stranded wires so you don’t have to carry multiple connector sizes. You can see through the connectors to inspect the connection and there are check ports you can stick a probe into to verify continuity.
Ideal claims they will make the SpliceLine Connectors in the USA in lots of 10, 100, 300, and 2500, but they haven’t yet released their pricing scheme.
