The HD007 multi-angle clamp mount can be used as a replacement, upgrade, or as an addition to an existing pedestal with a Dual-T mounting pattern. The mount is compatible with Arkon's universal smartphone and tablet holders (sold separately), including the Slim-Grip Universal Tablet Holder (TAB001), Universal Tablet Push Button Holder (TAB003), Mega Grip Universal Phone Holder (SM040-2), and Slim-Grip Ultra Universal Smartphone and Midsize Tablet Holder (SM060-2). This mount includes only Arkon's Heavy-Duty Aluminum Clamp Mount with 8'' Multi-Angle Arm and Dual-T Head (holders sold separately). This sturdy 8''mount features three adjustment knobs at 2.5'' intervals on the mount arm for easy positioning. Two additional 180 adjustment points at the top and bottom of the mount provide additional flexibility in positioning the device. The mount's C-Clamp opens to grip clampable surfaces such as tables, desks, and counters up to 1.75'' thick. Bend the 8'' multi-angle arm and rotate the swivel ball adapter head for 360 rotation for exact positioning of the device.
