RAM® 球頭支架 附圓形AMPS板與大圓板 - 中型

The double socket arm locks into place with a satisfying click, and the two different-sized bases give me flexibility for mounting on my boat or truck. I've already used it in rough waters and the phone stayed rock solid the whole time.

The pre-drilled holes on the 3.68" base lined up perfectly with my existing setup, so I didn't have to drill anything new. The double socket arm is stiff enough to hold my tablet steady on rough roads, which is exactly what I needed.

The double socket arm gives just the right amount of adjustability for my GPS setup, and the pre-drilled holes on the large plate made installation a breeze. It feels rock solid once tightened down.
