قاعدة مشبك نصف سكة RAM® للقضبان 1-1.25 بوصة

The rubber ball locks in tight with zero wobble once you tighten the knob, even on my aluminum railing. Took under five minutes to mount and it’s been rock solid through a week of rough water.

I've got thick 1.25" bars on my boat and this ball base grabs them solidly, no wobble even in chop. The rubber ball is exactly the right size to pair with my existing C-size cradle, so swapping devices takes seconds. Exactly what I needed for a clean install without cutting into the rail.

The rubber ball swivels just enough to position my phone perfectly without loosening, even when the lake gets choppy. I've used it on both a 1" and a 1.25" rail, and the clamp grips both securely. Took about two minutes to install.
