The RAM combination swing arm/tele-pole system will connect to any RAM vehicle base without a welded female tele-pole. Included is a tele-pole with a height range from 11.5" to 17"; it is easily 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 any RAM cradle, holder, or Tough Tray. The double swing arm with rotating plate allows you to twist and tilt the viewing angle of your laptop, tablet, or any other connected electronic device. This rotating swivel arm gives you even more viewing positions for your mounted electronic device while holding everything firmly in place. Made from powder-coated aluminum. 8" male/9" female tube. 12"L.
