RAM® 球體轉接器（附圓形板及1/4-20螺柱）- C尺寸

I needed a sturdy ball adapter for my GPS mount and the rubber ball combined with the threaded steel stud gives a rock-solid connection that hasn't loosened once. The 1.5" ball fits perfectly into my existing cradle and the round base feels very durable.

The 2.5" round base sits perfectly flat on my workbench, giving the whole mount a solid, wobble-free feel. Even with a heavy tablet attached, the rubber ball holds it firmly in place without any slip.

The threaded 1/4"-20 stud is exactly what I needed to mount my GPS, and the rubber ball holds tight even on bumpy roads. That round base provides a solid, wobble-free foundation for my setup.
