221-2401 | WAGO Lever-Nuts® Inline Splicing Connector | for Solid and Stranded Conductors | 2-Conductor with Operating levers | 20-12 AWG | Transparent housing | White Cover | [Box of 60 Pieces]

Having an inline splice is handy for splicing automotive wires. The big advantage is that they can be weatherproofed with heat shrink tubing. Good spring tension, watch out for imitations, WAGO is the original and the best !

These are perfect for tight areas. Great quality product.

Easy to use. Might use them to rewire my stock trailer

work great, just like they should. wish I could find locally easier so I didnt have to wait on a project

Good quality product.

Does what its supposed to

These are the ones needed for 12 ga wire. Wagos make splices and joining wires easy.

I had originally purchased a variety pack of Wago lever nuts to use for smart switch installations in my home. The variety pack contained the side by side 221-412 style for two wire connections - I quickly depleted those as many smart switches have wire leads and the side by side style quickly got used up for line/load black leads and neutral white leads (for those switches requiring neutrals). Looking to replenish the side by side two wire connectors, I instead sought out this newer (at least to me) 221-2401 inline style connector, as I had seen it in use in a couple Tech Tuber smart home installation videos. I found though that based on the specifics of each individual installation, both the side-by-side and inline styles have their particular use case. I actually prefer the side-by-side style if installing in a busy box - the side-by-side tend to lay up better in my opinion when pushing the wiring back in to the switch box. The inline connecters are preferable in a couple situations, including installing an overhead light fixture or extending overly short wires in a switch box. For overhead fixtures, the inlines are easier to snap on to the house wiring, and then bring the fixture up to the open end of the inline connector and snap the fixture leads to the house wiring (the side-by-sides have you fighting gravity a bit as the fixture leads need to be brought parallel to the side-by-side connector). I also have a switch leg switch box where the original ground wire was left overly short by the original electrician when the house was constructed - these inline style connectors are perfect for attaching to a short wire first, before any other connections are made, and then the wire lead from the smart switch can be easily snapped in - in this case, with a short house wire, the inlines dont fight being pushed back in to the box like they do when using the inlines with reasonable length house wiring. So in summary, both these inlines and side-by-sides are good and have their uses - I may have gotten a lower count inline box knowing what I know now, as I think the frequency of use of these will be lower than the side-by-side usage.

Best product! Works perfect!

Awesome
