Just when you thought you'd seen the epitome of user-friendly adaptability, RAM Mount introduces a new level of innovation that raises the bar well into the stratosphere. With its RAM Double Socket Swivel Arm for 1" Balls, RAM Mount debuts a never-before-seen degree of flexibility that delivers even more versatility to users of its cradles and mounting bases. Fabricated from high-strength composite materials, this revolutionary arm boasts a pair of 1" diameter open sockets - one at each end - designed to seamlessly connect with the 1" rubber ball common to several mounts & cradles in the RAM lineup. Each socket features its own control knob, enabling users to independently adjust the tension/position of each joint. In addition, this one-of-a-kind arm boasts a 360° rotation point at its center, which allows operators even more positional control than was possible on previous models. Together, the sockets and central rotation offer virtually unlimited arrangement options. A phenomenal product for a level of control you must experience to believe.
