What is the ball dimensions in our Dual Pivot Arms
Can I combine multiple arms, for example, an extension arm and a small dual-pivot arm?
Yes since all the arms have 360 connections on them you could theoretically link as many arms together as you’d like, though it's worth considering the leverage that this will place on the base of the mount once a phone is attached.
Can I use a Dual Pivot Arm with my existing ball mount from a 3rd party brand?
The Dual Pivot Arms contain 22mm pivot balls, which aren't interchangeable with most ball mounts on the market which typically come in 25mm.
