RAM® 雙球頭臂（附固定旋鈕）- B尺寸 長型

I needed a longer reach for my setup, and this double socket arm gives me exactly the right positioning flexibility with its single spring retention knob. The ball sockets hold tight without any wobble, even on bumpy roads.

The sockets grip the ball mounts firmly with no wobble, even on bumpy roads. That single spring inside makes adjusting the angle effortless while still holding my tablet securely.

The spring-loaded retention knob makes swapping out my GPS mount so much quicker than with the old thumb screw versions. Installed this on my motorcycle handlebars and it hasn't budged an inch after a few hundred miles of bumpy roads.
