221-2401 | WAGO Lever-Nuts® Inline Splicing Connector | for Solid and Stranded Conductors | 2-Conductor with Operating levers | 24-12 AWG | Transparent housing | White Cover | [Box of 60 Pieces]

These devices are very easy to use to connect electric wires together. I use them in place of wire nuts because you can disconnect wires quickly with out damaging the wires. Easy to make quick connections that hold. They come in different configurations to connect 2 or multi wires together..

The foot dimmer switch on my floor lamp broke. Rather than replace it, I chose to remove it altogether and just splice together the wires.I considered soldering the wires together or using traditional butt connectors. I didn't have enough space or excess wire to properly solder, and I didn't want to buy crimpers for butt connectors. Wago connectors turned out to be a perfect solution -- no additional tools, only needed 0.5" of stripped wire, and no risk of screwing it up.

I’ve been using regular Wago connectors for years and consider them superior to wire nuts. Having an inline version is great. However, I would recommend wrapping the release tabs with electrical tape to prevent unintended opening due to snagging (it’s happened to me.) Much faster, easier and takes up less space in a crowded box.

Used for a ham radio project, they seem to lock up well against 26 to 14awg wires no issue. Better than cheap crimp on connectors of using expensive single use connectors.

Splices two wire ends together without a nut. These arrived quickly.great company. Just strip off the amount of shielding that is shown on each splice an lock to hold joint

Easy to use. Holds wire securely.

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 don't "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.

Holy crapanolla these are awesome! They work and they are easy to use.
