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]

These are super easy to use, but you better make sure that power is off first before you try to fix the dishwasher or else youre in for the SHOCK of your life.

Where have these things been my whole life? I do a TON of home and auto AV work as a hobby, and just discovered these things. Ive used the other Wago connectors periodically, which are also great, but these inline connectors take layout and spacing possibilities to a whole other level. Additionally, they allow me to quickly and safely test new runs/connections prior to permanently installing them, even I ultimately use a different permanent connector.

Used this to join cables from 20 to 16gauge and in between in relation to automotive head unit radios harnesses and wiring in accessories. Makes life much easier especially for testing connections since you can flip the lever up and down to install and remove the wires. Tight grip on single and multiple cables and more secure than the wire nut caps. Side note: you can connect multiple wires by double joining on a side and then connect the 3rd or a 2nd pair on the other end. Only do so if its safe naturally but it is possible for a 3/4 way connection.

Im using them everywhere now, along with the normal Wago 221s depending on the situation. Did I say that these things are freaking awesome? Yes I did.

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.

I purchased this product on the recommendation of Youtuber and Amazon store owner EverydayHomeRepairs. In an earlier review for this same product but within a box of variable sizes, I stated that I liked this product (WAGO wire connectors) so much that I shared them with my neighbors. Well! My next door neighbor came by and told me that he used what I gave him when he began upgrading pocket lights in his family room, and he liked them so much, that he ordered more to use for the rest of the lights that he is upgrading in his home! Theyre literally a snap to use; a small tug on the wire ensures grip, and you can view the connection and even photograph it right through the connector! Makes DIY fun again!

HAS A STRONG LEVER

Larger than expected, high quality though.

Does what its supposed to

Ive used these connecters in the past and they work very well. Whether it is stranded wires or solid wires and wires of different thicknesses, these connecters hold the wires good to ensure good contact between wires. Much easier to use than twist on wire nuts. I would recommend them to others.
