The RAM-B-121U consists of a double socket arm, round 2.5 inch base that contains the universal AMPs hole pattern and yoke clamp base. The clamp base will accommodate rails in diameter from 0.625 inch to 1.25 inch. The 1 inch rubber ball is at a right angle to the plane of the mount so when connected to a rail, the ball sits parallel to the rail.
