RAM® ダブルソケットアーム（保持ノブ付き） - Bサイズ ショート

So glad I grabbed the short version instead of the longer one, the 1" ball sockets on both ends lock in tight with zero wobble, and that knob extension on the side makes tweaking the angle a one-hand job even with gloves on.

The retention knob makes adjusting the angle on my GPS mount incredibly easy, even while driving. I was surprised how much sturdier the short arm feels compared to the longer version. This little double socket arm is exactly what I needed to keep everything tight and secure.

The double socket design is handy for quick ball-mount swaps, and the retention knob makes adjustments feel solid without needing a tool. Only gripe is the short length limits positioning in tight spots, but it works as intended for a compact setup.
