RAM Double 1" Ball Swivel (RAP-B-230-1U)

Used to join two double arm sockets. I needed an elbow that was adjustable. Seemed to meet the requirements, but introduced too much flex which translated to the phone and holder bouncing. Ended up changing for a double socket with built in swivel.

I was looking for the solid 1"-1" ball which was out of stock when the swivel setup was shown to me. Not only will it do the job of the fixed ball to ball but the swivel allows almost unlimited possibility of mountain GPS,Phone,Go pro by avoiding brake and clutch cylinder's, cables and instruments. The price make this valuable addition even more attractive. The sturdy construction will be tested in the Himalayas shortly but it looks to be up to the job
