WAGO 221 Lever-Nuts

WAGO Lever-Nuts, specifically the 221 series pictured, are a modern alternative to traditional wire nuts used for connecting and splicing electrical conductors. Originally invented in Germany, the lever-actuated design allows for tool-free, reusable, and secure connections for solid, stranded, and fine-stranded wires.

The product is manufactured by WAGO GmbH & Co. KG, a family-owned company with its global headquarters in Minden, Germany. While many of their core electrical connection components are manufactured in German facilities, WAGO operates a global production network with major sites in Switzerland, Poland, China, India, and the United States to serve regional markets.

WAGO remains an independent, family-owned entity. It was founded in 1951 by Friedrich Hohorst and Berthold Koch. Today, it is a global leader in spring pressure connection technology and automation solutions, maintaining its status as an influential private company within the electrical engineering industry.
