This double ball rail base accommodates rails from 2" to 2.5" in diameter. With two C size 1.5" diameter ball adapters, you can attach two C size socket arms for mounting multiple devices off of one base. This minimizes the need for multiple attachment points needed for a multi-device mounting system; ideal for forklift mounting with minimal available space.

Julian T. ★★★★★ Oct 23, 2026

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.

George ★★★★★ Oct 20, 2026

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.

Charlotte Y. ★★★★★ Oct 18, 2026

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.
