The 221 Series from WAGO provides flexible, fast and safe connections. 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. Setting new standards in electrical installation, the 221 Series LEVER-NUTS splicing connector is now smaller, more user-friendly and made for larger conductors.
