RAM® 圓形平台底座（AMPS 孔位）

The four-hole AMPS pattern lines up perfectly with my existing hardware, so installation took under two minutes. Solid, stable, and exactly what I needed for a clean desk setup.

Finally, a desk mount base that doesn't wobble under a 15-inch tablet. The AMPS hole pattern gave me zero hassle aligning with my existing arm, and the round profile sits flush without taking up extra space. Solid enough that I don't think about it, which is exactly what I wanted.

The AMPS hole pattern lined up perfectly with my existing mount, and the anodized finish feels industrial-grade. I was worried about the diameter being too small, but it holds my tablet steady even on bumpy roads. Exactly what I needed for a clean desktop install.
