Banana plugs greatly simplify the speaker installation process. These open screw-type plugs are suitable for bare wire, shovel connections or other types of banana plugs. For easy polarity identification, each set includes one red and one black coded plug. The plug's gold-plated surface helps resist corrosion and ensures a smooth connection. To install, simply insert the wires into the holes on the bottom of the plugs and tighten the small internal screws. Make sure the screws are tight to prevent loosening and keep the wires in steady contact. These well-designed plugs make it easy to connect devices.
