RAM® ダブルボールマウント ダイヤモンドプレート & 1/4"-20 メネジポスト

That Diamond Ball Base locks in tight and the arm holds my device steady on rough roads, no wobble at all. I mounted it in my truck and the medium length arm positions everything exactly where I need it.

The 1/4"-20 threaded post on this mount made attaching my dash cam bracket much easier than past setups. The arm feels sturdy once you tighten the knobs, though I wish it came with a shorter option for tighter spaces.

The 1/4"-20 female threaded post let me attach my camera rig without any adapter issues, which was a nice bonus. Setup took a few extra minutes because the ball arm is a bit stiff to adjust, but once it's in place it holds firm.
