قاعدة RAM® Rail Clamp المزدوجة الكروية للسكك الحديدية 2" - 2.5"

The double ball design lets me attach both my phone and GPS mount to the same rail clamp, which cleans up my handlebars nicely. It grips my 2.25-inch roll bar tightly without any slippage during rough rides.

Clamped this onto my 2.25" tubular rail and both ball adapters held firm even on a bumpy road. Finally, a clean way to mount two phone holders side by side.

Took a chance on this for a rooftop rail setup, and the double ball design is exactly what I needed to angle two arms independently. The clamp tightened down solid on my 2.25" rail without any wobble, and the two 1.5" balls give me plenty of freedom to position my phone and action cam just right.
