RAM-B-273U RAM 1" Add-A-Ballâ„¢ Accessory Base for any B-size Socket Arm

Connect another device to your existing RAM® Mount with the RAM-B-273U Ball Base Adapter. This ball is made up of a 1" ball connecting to a 1/4"-20 threaded stud with a length of 1.6". The threads on this ball replace the bolt in any B-size socket arm, and the ball connects 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 the ideal accessory for connecting both devices off of one mounting base.
