Safely mount your compatible smartphone with the Composite Flat Surface Mount with Universal X-Grip Holder from RAM MOUNTS. This mount features a 2.5" diameter round base with the universal AMPS hole pattern, a double socket arm, and a universal spring-loaded X-Grip holder. At each end of the socket arm is a 1" diameter rubber ball and socket system with adjustment points. When the arm knob is twisted, the joints at both ends become flexible, so you can move the mount to the desired viewing position. Once adjusted, the arm knob can be tightened to lock the movement of the joints, ensuring your device is secured safely in place.
