Banana plugs make speaker installation a breeze. They are designed for use with amplifiers or speakers that use traditional binding posts. Not only is it easier to make the connection on the back of your amp; it is safer; with no chance of stray wire strands creating a short across contacts. This high-quality dual plug has two banana plugs spaced 3/4" center-to-center with a red plastic yoke; the typical distance between binding posts on speakers. The plugs are the open screw type and can accept bare wire; spades; or other banana plugs. They are sized to fit speaker wire from 12 to 18 AWG. Each pair comes with one plug color coded red and the other coded black; for easy polarity identification. The plug body is made of brass; which is then plated with gold to help prevent corrosion and ensure smooth connections. Features: Can accept bare wire; spades; or other banana plugs Can accept 12 to 18 AWG speaker wires Color coded black/red rings for maintaining proper polarity Secure; positive contact with binding posts Corrosion resistant; 24K gold plated brass plug Red plastic binding yoke
