RAM® 水平旋轉支架，附插座臂

I needed a sturdy mount for my tablet in the truck, and this socket arm’s horizontal swivel is smooth enough to adjust one-handed while driving. The included ball studs let me align it perfectly without any wobble.

Installed this on my boat's console for my fish finder, and the D size 2.25" socket arm holds it steady even when I hit rough wakes. Adjusting the swivel is quick and tool-free, which is exactly what I needed.

The socket arm locks tight with zero wobble once you crank it down, and that 2.25" ball gives plenty of adjustability for positioning. I've been using it daily for a week straight and it hasn't budged an inch.
