The RAM Quick-Grip Flat Surface Mount consists of a 2-hole diamond drill-down base, a double socket arm and spring loaded cradle for supporting most phones. Integrating the industry standard AMPS hole pattern, this mount can connect to any flat surface or to the side of the RAM Tough-Tray. The double ball and socket design provides adjustment points at both ends of the socket arm with the turn of a single knob, allowing you to set your phone to the optimal viewing position.
