Description
Maintenance-Free Junction Box for Wago 221-4 Connectors
Connexbox® 221-4 previously sold as 207-3301
The Connexbox 221-4 junction box is a compact maintenance free enclosure designed for fast safe and professional cable connections using Wago 221-4xx lever connectors and selected Wago PushWire connectors. Formerly sold as 207-3301 this product remains unchanged in design performance and compliance and continues to be manufactured by the same UK based team that originally developed the widely used grey junction box range.
Following a brand transition these trusted enclosures are now sold under the Connexbox name. This move allows Connexbox to operate independently while maintaining the same tooling materials and quality standards electricians rely on. For installers and wholesalers the reassurance is simple the product you know is exactly the same only the branding and reference have changed.
Designed with electricians in mind the Connexbox 221-4 allows cables to be terminated before being placed into the enclosure improving installation speed consistency and on site safety. Its compact size secure cable retention and maintenance free certification make it ideal for concealed or inaccessible connections in domestic and commercial installations.
