The RAM-B-121-A-202 consists of a yoke clamp base, SHORT length double socket arm and round
2.5" base that contains the universal AMPs hole pattern. The yoke clamp base will fit rails
in diameter from 0.625" to a maximum of 1.25". The 1" rubber ball is at a right angle to the
plane of the mount; when connected to a rail, the ball sits parallel to the rail. The mount
is designed with a RAM 1" diameter patented rubber ball and socket system that has adjustment
points at both ends of the double socket arm, allowing for almost infinite adjustment and
perfect viewing angles.
