The Scosche UH4EX22PK-XC0 ExtendoMount Non-Magnetic Car Phone Mount holder system with telescoping adjustable mount arm is for conveniently mounting your Smartphone devices to your vehicle's dashboard or windshield in your car, truck, boat or RV. Every vehicle and driver are different; That’s why the telescope phone mount adjusts to perfectly suit each one. Securing your device is easy: just place it between the adjustable arms and lock securely in place. The mount arms accommodate any device, up to 3.5 Inch wide. The telescoping mount arm extends/contracts forward to back from a range of 5.34 Inch to 8.87 Inch with a 220-Degree angle, so you can move the arm to your desired length. Lock the GPS mount into place on the most firm and flat surfaces using the StickGrip bottom or suction cup mount included bases. Using the 360-Degree rotating ball-joint head, adjust the car phone mount holder with an iPhone, Android or any other mobile device seamlessly between portrait and landscape orientation in a snap.
