RAM® ダブルボールマウント メタルノブ付き - Cサイズショート

The metal knob gives you way better grip than those plastic ones when you're tightening it down. The double socket arm is rock-solid once locked in place - zero wobble even on bumpy roads.

I needed more adjustability for my tablet mount, and the 3 inch double socket arm gives me just the right reach without being flimsy. The rubber ball grips hold position perfectly even on bumpy roads.

The metal knob lets me tighten it securely by hand, no tools needed. This double socket arm holds my device steady even on rough roads. Very pleased with the solid build.
