RAM® 12 吋鎖定式雙擺臂（附圓形底座）

Installed this on my boat’s console to hold a tablet, and the locking mechanism clicks into place solidly—zero rattling even in choppy water. The 12" arms give plenty of reach without sagging.

The arm swings with a satisfying amount of resistance, so it holds position without feeling stiff, and the locking mechanism engages with a solid thud every time. I’ve had it bolted to my dash for a week now and it hasn’t budged an inch, even over rough pavement.

The locking mechanism clicks in place with zero wobble, and the 12-inch arm holds my tablet exactly where I need it on the truck dashboard. Took a few minutes to tighten the round plate, but now it’s rock solid even on rough gravel roads.
