The RAM-109H-2BU consists of a 6" long STRAIGHT swing arm mounted on a horizontal surface mounting base. At the free end of the mount swing arm is a round 1.5" diameter ball. The connection between the swing arm and the base is a bolt pivot point, and the round plate and arm connection is the RAM ball and socket system. The bolt pivoting point allows a complete 360 degree rotation and the ball and socket system allows a 180 degree vertical pivot with a 360 degree rotation.
