Pull the lever up, insert a conductor and push the lever back down – done! As tool-free, lever-actuated connectors, WAGO's 221 Series Splicing Connectors easily, quickly and safely connect solid, stranded and fine-stranded conductors ranging from 24–12 AWG for 221-41x, 20-12 AWG solid for 221-2401 inline. Setting new standards in electrical installation, the 221 Series LEVER NUTS splicing connector is now smaller, more user-friendly and made for larger conductors.
