In this overview, Bettermann ZU 20-AS Halogen-Free Spacer Connector for Flush-Mounted Junction Boxes is compared with various electrical accessories by Bettermann, such as a steel cable clamp, cable tray covers, and mounting DIN rails. All these products are intended for professional electrical wiring and cable management installations, but they serve completely different functions: the spacer connector ensures precise spacing between junction boxes, while the alternative products are used for cable retention, tray protection, or mounting modular equipment.
