RAM® 垂直導軌支架，附12吋雙擺臂與圓形底板

The double swing arms let me position my tablet exactly where I need it, even on a bumpy boat ride. Install was straightforward, and the whole setup feels rock solid.

I was a bit worried about stability on a vertical rail, but the round plate locks down tight with zero wobble even on rough roads. The 12-inch arms give me exactly the reach I needed to swing my device clear when accessing controls underneath.

Finally got this mounted on a boat railing and the double swing arms make it incredibly easy to adjust my tablet's angle. The 12-inch reach is just right for keeping the screen close without blocking the walkway.
