The RAM-B-201U-C-ALA1, LONG length double socket arm with retention knob, has a socket at both ends that accommodates 1" ball bases. A single spring inside the arm opens the end sockets, allowing you to pivot the ball and socket connection. The knob extension allows for easy adjustment of the mount and prevents over loosening of the knob. This socket technology allows for almost infinite adjustment and perfect viewing angles.
