The car seat or floor mount is ideal for those who want a phone holder for a truck but prefer mounting it somewhere other than the windshield or dash. This mount includes Arkon's universal locking tablet holder and 18" flexible aluminum gooseneck floor mount with 25mm (1 inch) ball-compatible Robust Mount Shaft. The universal locking tablet holder features a key lock (keys included) that keeps the tablet securely in place. The tablet holder is made of aluminum and includes multiple horizontal and vertical adjustment points along both sides, making it compatible with tablets as small as the G Pad 7.0, or as large as the Nexus 10. Use a 7mm and 10mm socket wrench to adjust the tablet holder to your tablet's size specifications. Security hardware is also included.
