Description 10-4! Our CB holder with a 20mm ball attaches to any of our standard mounting arms to keep your CB Radio microphone handy while out on the trail. Please note – we recommend pairing our CB Holder with our Micro, 1cm, 4cm, 7cm or 10cm mounting arms. Anything longer will put too much stress on the ball joints, especially if positioned horizontally. **PATENT PENDING**
