The mount is extremely heavy duty.  Swivel adjustments at the base and holder as well as a third adjustment in the middle.  This comes with a C-Clamp that expands up to 1.75".

The C-Clamp base allows mounting on most flat-edged tables, desks, counters, or other flat-edged surfaces. .  The mount has a dual T ending to fit many of Arkon's adapters and cradles.
