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.

Miles ★★★★★

The 1-inch ball locks into my existing mount perfectly, and the threaded stud screwed right in without any wobble. It’s a simple, solid way to add another phone holder to my setup.

George B. ★★★★★

Didn’t realize how handy the 1.6-inch threaded stud would be until I mounted a second device onto my existing arm setup. The 1” ball clicks in just as solidly as the original, so no wobble on rough roads. Exactly what I needed to expand my rig without buying a whole new system.

Steven S. ★★★★★

Adding a second phone mount to my existing rig was a breeze with this threaded ball adapter. The 1/4"-20 stud threaded perfectly into my arm, and the 1-inch ball holds my tablet securely.
