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.
