RAM® 球頭底座 for Crown Work Assist® - B尺寸

The custom hole pattern matched the Crown perfectly, no drilling or adapters needed. The ball base clicks into my existing B-size arm without any wobble, even on bumpy warehouse floors.

Bolted it onto the Crown Work Assist in about five minutes, and the B size ball fits my existing RAM arm perfectly. The custom hole pattern aligns exactly with the vehicle's mount, zero drilling or adapters needed. Solid, wobble-free connection even with a heavy tablet attached.

The mounting holes match the Crown Work Assist base exactly—no drilling or shimming needed, which saved me a headache. The ball joint is snug and holds my tablet arm steady even when I hit bumps.
