Solid construction 4 mm stackable banana connectors with multistrand copper wire and colorcoded design for easy circuit identification. This arrangement provides a robust, reliable connection that helps prevent wiring errors during setup. Protective design PVC insulation for complete safety, strain comfort technology to prevent wire damage, and nickelplated connectors for corrosion resistance. The combination supports safer, longerlasting use in busy test environments. Universal application Suitable for multimeters, power supplies, and lab equipment connections; works with standard 4 mm banana jacks; ideal for testing electronics. Offers broad compatibility across common lab tools and test rigs. Thoughtful design Stackable connector feature enables multiple connections at one point; springloaded contact points ensure a stable connection; flexible, tangle cable for organized bench layouts. Use scenarios electronics bench testing with a DC power supply and a meter: connect a circuit to monitor voltage and current quickly with colorcoded, stackable banana connectors for clear wiring. prototyping and lab experiments: link components and test setups securely using springloaded contacts, facilitating repeatable measurements and tidy cable management. education and demonstrations: teach safe wiring practices, colorcoded identification, and multiconnection configurations in classroom or workshop environments.
