RAM® 雙球接頭臂無旋鈕 - B尺寸中型

The spring-loaded sockets snap onto 1" balls with a satisfying click, and the whole arm holds its position even on bumpy roads. I've had cheaper mounts before that sagged within a week, but this one hasn't budged since I installed it.

I needed a secure yet adjustable way to mount my tablet in the truck, and the spring-loaded pivoting mechanism on this socket arm lets me position it perfectly without any loosening.

The double ball sockets grip firmly even on my bumpy boat rides, and the lack of a knob means nothing snags on my gear. Installation took maybe two minutes with the included hardware. This arm feels solid enough to hold my GPS unit steady in any weather.
