Wago 221 Series Lever-Nuts

Simply lift the lever, insert stripped wire in the slot, and lower the lever. No tools necessary!

The Wago 221 series allows solid, stranded, and fine-stranded wires to make a reliable connection faster than ever before. These lever-nuts also save space in junction boxes because of their new compact design which is 40 percent smaller then the Wago 222 series. The Wago 221 series also features a transparent housing which allows for users to clearly see if the wires are connected properly and stripped to the correct length.

The Wago 221 series lever nut uses cage clamp technology to secure and insulate conductors from hazards that could interrupt electrical operation and pose a threat to safety. The levers allow release tension when raised, and clamp down when closed.
