Top quality heavy duty splicer
The ones with the white part in the middle are super convenient for connecting two wires. They are simple and work very well, especially in a narrow electrical box.

Perfect Fix for Emergency Brake Wiring on Our Aliner Expedition
We needed a reliable and quick solution for an emergency brake wire connection on our Aliner Expedition camper, and these WAGO lever nuts delivered! The compact design made installation in a tight space super easy, and the levers lock down snugly, giving us confidence in the connection’s security. No tools, no twisting wires—just a clean, professional result in seconds. The included case is a nice bonus for storage and future projects. Highly recommend for RV repairs or any wiring job where reliability and ease-of-use matter.

Quick, convenient and secure
These are easy to use, quick and convenient electrical connectors. I don't have to fumble with trying to get the wires secure and connected in a wire nut, or butt connectors. The wires seem really secure once they are snapped in. And, they are reusable unlike butt connectors that you have to Crimps. Ill be keeping a supply of these in my toolbox.
