RAM-B-273U 1" Ball Accessory Base for any B-size Socket Arm

Want to add a second device to your setup? Add an extra mounting ball to the side of your existing B-sized (1" ball) arm with this handy stud.

This ball is made up of a 1" ball connecting to a 1/4"-20 threaded stud with a 40mm long thread. The threads on this ball replace the bolt in any B-size socket arm, and mounts the ball to the middle of the socket arm on the opposite side of the tightening knob.

If you are looking to mount more than one device but cannot locate multiple mounting points on your motorcycle or vehicle, this base is for you.
