This mount includes Arkon’s universal locking phone holder and 18 inch flexible aluminum gooseneck floor mount with 25mm (1 inch) ball-compatible Robust Mount Shaft. Arkon's Robust locking seat rail or floor phone mount fits phones 4.88 inches up to 7.18 inches tall and 2.37 inches to 3.94 inches wide, including Apple iPhone 12 Pro Max, iPhone 12 Pro, iPhone 12, iPhone 12 mini, iPhone 11 Pro Max, iPhone 11 Pro, iPhone 11, iPhone XS Max, iPhone XS, iPhone XR, iPhone X, Samsung Galaxy S21, S20, S10, and S9, Galaxy Note 20, Note 10, and Note 9, Google Nexus 6 and Nexus 5. Use a Phillips screwdriver to set the phone holder’s height and width to your phone’s size specifications. (Mount your phone in the landscape position and rotate the holder for portrait viewing.) The universal locking phone holder features a key lock (keys included) that keeps the phone secure. The car seat or floor mount is ideal for those who want a phone holder for the car or truck but prefer mounting it somewhere other than the windshield or dash. Security hardware is also included to help prevent theft. Install the mount to the car’s seat rail with a socket wrench by loosening the passenger seat track bolt, inserting the seat track bolt bracket, and retightening the seat track bolt. Bend the mount’s 18” gooseneck and adjust both of the mount’s double-ball adjustment points for 360-degree rotation of the phone. Including the Robust mount shaft arm, this mount measures 21.5 inches from end to end. Optional floor brackets are included for screwing the car dock directly into the floor of the vehicle. (Warning: Drilling into the vehicle’s floor may damage the vehicle. Use caution and consult a mobile install professional to avoid drilling into any sensitive vehicle components.)
