The RAM-B-103U-C consists of a 2.5" round base and LONG double socket arm that will accept 1"
ball bases. The round base contains pre-drilled holes, including the universal AMPS hole
pattern. Designed into the mount is a 1" diameter patented rubber ball and socket system with
adjustment points at both ends of the socket arm; this with a twist of the arm knob allows
for you to maneuver the mount to your optimum viewing position.
