RAM® 重型 C 型夾底座，附旋轉棘輪臂與球頭 - C 尺寸

I was a bit worried about how stable a clamp mount would actually be, but the ratchet arm really locks down tight with zero wobble, even on bumpy roads.

The swivel ratchet arm makes angling my tablet effortless, and the clamp base holds firm even on a thick desk edge. I was expecting a wobble, but the ball joint locks tight. Great buy for a non-permanent setup.

The knurled knob on the clamp base makes tightening it onto a table edge a quick, tool-free job, and the ball-and-socket swivel holds my device steady at any angle. Only gripe is it’s a bit of a wrestle to get the ratchet arm fully loosened when I want to reposition, but once it’s set, it’s solid.
