Ram mounts tele-pole w/ 12in & 9in poles, double swing arms & round plate

The RAM-VP-SW1-129 consists of a 9" 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™. The height of the Tele-Poles™, combined, 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 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".
