221-412 | WAGO 4MM² Compact Splicing CONNECTORS, 2-Conductor Connector with Operating LEVERS Transparent

I have fallen in love with Wagos and use them on every electrical project I can. I've been replacing light switches and receptacles and replace every wire nut with Wagos. They're simple, fast, and hold those wires tight. They're worth their weight in gold!

Easy to use and take up less space in junction boxes. I find them much safer and easier to use than wire nuts (and I've been using wire nuts for years). Great invention.

I bought these because they looked like an alternative to wire nuts. They are! In addition to being easy to use, they work with a wide range of wires, and consume less space than traditional wire nuts. A great addition to my electrical arsenal.

Wago’s make splices easier they take up less room in outlet or switch box.

These are the best thing ever! They hold the connection securely. I've had more trouble with wire nuts and wires slipping out just when you are ready to finish the project. These are awesome and NO more wire nuts for me!

This item works great. Twisting wire overhead is a pain. These make the job fast and painless. They have a very strong grip on the wires.

I just purchased another set of various sizes, I used them on an outdoor light fixture, because of having to adjust the screws I had to remove the fixture wires 3 times which would have been a nightmare with wire nuts, which cause having to twist and untwist the wiring causing the wire to break and having to strip the wire insulation back. With the Wagos it was so simple and no damage to the wire, also one wire being 12awg, and the other 18awg, they both remained tight in place.

I have used the two- three, and five-lead version of these, and they are a great invention. Unlike the Ideal product that is an inline joiner, these can be reopened to add, remove , or re-configure your wiring. I highly recommend them for installing things like timers and smart switches and dimmers that have their own leads; wire nuts can be frustrating, especially in tightly packed J-boxes. These take less space and lay flat.
