The Flexi-Rail W adapter is a compact and universal DIN-rail adapter for many retrofit relays, including several types of Shelly, Nous and Gledopto relay modules. This simplifies and speeds up the installation process of the relays into an electric cabinet with DIN-rail, while minimizing the risk of losing parts. In addition, it features practical side holders where WAGO connectors used for wiring can be securely placed.

The holder is a perfect solution for mounting on a standard 35 mm DIN rail, but it can also be attached to a wall or any flat surface using the two mounting holes. Made in Germany from flame-retardant PETG material using FDM technology.

Key Product Features
