RAM® Snap-Link™ ロングダブルボールアダプター

The 3-inch arm length is exactly what I needed to bridge the gap between my other mounts. The double balls lock in securely without any wobble, which is a huge improvement over cheaper setups I've tried.

My old ball mount had way too much play, but this 3-inch arm locks up solid between the two halves of my setup. The double balls at each end make alignment much easier than I expected at this price point.

It was a perfect fit for the setup I was building — the 3" arm length gave me just the right spacing between my phone mount and the base. The double balls at each end make positioning the device a breeze.
