RAM® 帶金屬旋鈕的雙插座臂 - C 尺寸中

I needed something sturdy for my GPS mount, and this arm's single spring design keeps tension exactly right so nothing wobbles on rough roads. The metal knob gives solid grip without needing tools, which beats the plastic ones I’ve dealt with before.

The spring-loaded sockets grip those 1.5" balls with zero wobble, and the metal knob makes adjustments feel solid and precise instead of flimsy. I've been swapping my device between two mounts daily and it hasn't loosened up at all over three weeks.

The metal knob on this double socket arm gives a much more secure grip than the plastic ones I've used before. It holds my device perfectly steady on the 1.5" ball mounts, even on bumpy roads.
