Ram mounts tele-pole w/ 12in & 18in poles, double swing arms & round plate

The RAM-VP-SW1-1218 consists of a 18" lower female Tele-Pole™, 12" upper male Tele-Pole™, double swing arm and 2.5" round base that contains the universal AMPs hole pattern. The lower female Tele-Pole™ will attach to all RAM vehicles bases that do not contain a welded female Tele-Pole™.
