Wago 221-412 Lever-Nuts 2-Conductor Compact Splicing Connector

Product Overview

The Wago 221-412 LEVER-NUTS® is a 2-conductor compact splicing connector engineered for the rapid, secure termination of solid, stranded, and fine-stranded electrical conductors. Utilizing Wago's proprietary cage clamp spring pressure technology, this connector establishes a gas-tight, vibration-proof connection without the need for specialized tools or traditional wire twisting mechanisms.

The transparent polycarbonate housing facilitates immediate visual confirmation of proper wire insertion depth and conductor seating. A highly compact footprint significantly reduces wire crowding within junction boxes, conduit bodies, and luminaire enclosures. Two integrated test ports enable voltage continuity testing without disconnecting the conductors.

Primary Applications: End-to-end inline splices, extending short conductors within junction boxes, single-fixture wiring, and general 2-wire terminations in residential, commercial, and industrial electrical systems.
