The RAM-VP-SW1-89-240 consists of a 9" lower female Tele-Pole™, 8" upper male Tele-Pole™, double swing arm and 3.68" round base. The lower female Tele-Pole™ will attach to all RAM vehicles bases that do not contain a welded female Tele-Pole™. The height of the Tele-Poles™, combinded, can easily be adjusted by turning the knob at the top of the post. Once the knob has been tightened, the Tele-Pole™ becomes a rigid support for connecting devices or cradles. The double swing arm allows you to twist and tilt the viewing angle of your connected electronic device, when mounted on your RAM Vehicle Mount. The rotating swivel arm gives you even more viewing positions for your mounted electronic device while holding everything firmly in place. The length of the double swing arm is 12". The 3.68" round base contains pre-drilled holes that connects to RAM Tough-Dock™ Powered Docking Stations.
