RAM® 三重磁性雙球支架 1/4"-20 螺紋柱

That 1/4"-20 male threaded stud on the ball base fits my action cam perfectly, making it rock-solid on bumpy trails. The short double socket arm keeps the whole setup nice and low profile on my dashboard.

The 2.5" round base with the triple magnetic adapter locks onto my car's metal roof rack instantly, and the short double socket arm holds my GoPro steady even on gravel roads. The 1/4"-20 threaded stud screwed on without any adapter fuss, which I appreciated. Setup took me under a minute.

The triple magnets hold my camera firmly even over rough gravel roads, and the double ball arm gives me perfect positioning angles. I was worried the 1/4"-20 stud wouldn't feel secure, but it threads in tight and hasn't budged at all.
