Overview
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.
Features
- Replace the bolt in any B size double socket arm to add another 1" B size RAM rubber ball to your mounting setup
- Included B size 1" RAM rubber ball allows for connection to any B size RAM double socket arm; ball and socket technology allows for near-infinite adjustability
- Made of powder-coated, marine-grade aluminium for durability and reliability in the most demanding environments
