The CM117-SBH long arm extension windshield suction car mounting pedestal can be used as a replacement or upgrade to a current Arkon mount pedestal. It is compatible with Arkon's universal smartphone and tablet holders (sold separately), including the Slim-Grip Ultra Universal Smartphone and Midsize Tablet Holder (SM060-2), Slim-Grip Universal Smartphone Holder (SM050-2), Slim-Grip Universal Tablet Holder (TAB001), and Mega Grip Universal Smartphone Holder (SM040-2). This mount package includes only Arkon's Rigid Long Extension Windshield Suction Pedestal with Telescoping Arm (holders sold separately). The suction pedestal installs easily to the windshield. Simply hold the base against the mounting area and push down on the one-touch lever. The sturdy telescopic arm of the pedestal extends from 14.5 inches to 18.5 inches, keeping the smartphone or midsize tablet within easy reach. For complete mount solutions, Arkon recommends the Universal Tablet Windshield Suction Extension Mount (TAB-CM117) for mounting a large tablet, or the Rigid Extension Windshield Suction Mount with Telescoping Arm (SM6-CM117) for mounting smartphones and midsize tablets. Both products are available on Amazon.
