Splice Wire Connector, 12 AWG Max, 2 Port, Transparent, Polycarbonate Insulation, 600 V, 32 A - 1 Each

I don't say this lightly: the WAGO 221-412 Lever-Nuts 2-Conductor Compact Splicing Connectors are, without a doubt, the single best thing ever invented for anyone doing home electrical wiring, DIY projects, or professional work. They have completely revolutionized how I approach splicing and connecting wires. If you are tired of fiddling with traditional wire nuts, you absolutely need to switch to these. The small lever design makes connections incredibly fast, secure, and, most importantly, reusable. You simply lift the orange lever, insert the stripped wire, and push the lever back down—you get a perfect, vibration-proof connection every single time, in a fraction of the time it takes to twist a traditional wire cap. The compact size of the 221 series is perfect for fitting into tight junction boxes, and the transparent casing is a game-changer. Being able to visually confirm that your wire is stripped to the correct length and fully seated ensures safety and compliance, eliminating guesswork entirely. For reliable, fast, and secure connections, WAGO Lever-Nuts are the standard, and I will never go back to twisting plastic nuts again. Pros: Unbelievably Fast: Makes splicing connections instant. 100% Secure: Creates a rock-solid, reliable connection. Visual Confirmation: Clear housing allows you to check the connection. Reusable: Excellent for temporary setups or adding/removing circuits easily.

the WAGO Lever Nuts are incredibly easy to use, even for someone like me who doesn't have an extensive background in electrical work. These connectors have eliminated the need for traditional wire nuts or terminal blocks that can be time-consuming and often require specialized tools. With the simple flip of a lever, the WAGO Lever Nuts securely and safely connect the wires, making the entire process quick and stress-free. One of the standout features of these Lever Nuts is their versatility. Whether it's solid or stranded wires, different wire gauges, or even mixing wire types, these connectors handle it all with ease. The robust design ensures a secure and dependable connection, eliminating any worry about loose or unreliable connections that can disrupt electrical flow. This versatility makes them a go-to choice for a wide range of electrical projects. Additionally, the compact size of the WAGO Lever Nuts is a major advantage. Their space-saving design allows for easy installation even in tight spaces, making them ideal for both professional electricians and DIY enthusiasts alike. Don't let their small size fool you – these connectors pack a powerful punch in terms of performance. Furthermore, the durability and reliability of these connectors are truly commendable. The high-quality materials used in their construction ensure longevity and stable performance, offering peace of mind that your electrical connections will remain secure over time. The reliable connection provided by WAGO Lever Nuts translates into fewer troubleshooting headaches and ensures a safer and more efficient electrical system.

Love these lever-nuts. So much easier to use than twist-on wire connectors. They provide confidence that the connections are safe and secure. Of course, I am not a professional, but I highly recommend these for the average DIYer ! They come in a variety of sizes depending on your needs.

Review: I recently started using the WAGO 221-412 Lever-Nuts, and I can honestly say they’ve made my wiring projects much faster and more reliable. The clear housing lets me see that the wires are seated correctly, which adds peace of mind compared to traditional twist connectors. The levers snap down firmly, and the connection feels secure with no wiggle or looseness. What I really like is how versatile they are — they work well with both solid and stranded wire, and you can easily disconnect and reconnect without damaging the conductors. This has been especially useful when I need to adjust or troubleshoot circuits without cutting off wire ends. A small downside is that they’re a bit bulkier than a standard wire nut, so in very tight boxes you have to plan ahead. That said, the tradeoff in ease of use and reliability is worth it. Overall, these connectors are a fantastic choice for anyone who wants a cleaner, safer, and more efficient way to splice wires. Once you try them, it’s hard to go back to the old way.

I'm incredibly happy with this purchase. Previously I used waterproof wire-nuts for my irrigation timer wire for my sprinklers. The wire nuts would somehow fall off; it seemed every time the gardener came. I tried a couple of other brands of quick-connect; including one that did not require any spicing and had built in waterproofing; but they proofed unreliable. I've had great success with the WAGO 221 in-line connectors. They were super easy to install and I like that they are reusable. I was able to water proof them with the WAGO Gelbox 207. I found that one gelbox held 3 connectors and I needed a separate gelbox to hold the groundwire connector where I used the 5 terminal version. (I only needded 3, but ChatGPT recommended I get the 5 for dependability). At first I thought it would be difficult to deal with seperate in-line connectors and gelbox for the water proofing; but after doing the installation I can say this was the easiest and fastest of the solutions. My connections feel solid, protected and if I ever need to change the wiring I can do so without buying new connector hardware! Also I was concerned that the gel boxes would be too big or cumbersome, but that turned out not to be the case at all. The gel boxes fit nicely around the connectors are are not bulky.

Pro’s : Excellent as far as ease of use . My arthritic hands appreciated not having to screw on wire nuts while standing on ladder. Con’s : Two of the locking levers snapped off with just normal pressure while being opened . Recommend using electrical tape to insure the orange locking levers don’t open on their own . I had to redo one connection because the never opened and the wire came out .

Accurate description, great product, great price, super fast shipping makes for a happy buyer.

Bought these for a 3d printer build. Worked great for the small spaces and make it super easy to rout the wiring cleanly around the machine to keep it looking professional. Super easy to use and great bang for your buck.

Great product to connect electric cables Saves you time amending the cables and replaces terminal connectors make it easy and safe for electric connections. They are small and the price is very attractive Used them in my living room and dinning room ceiling lights and in seconds all was safely connected Recommend 5* product
