최대 3인치 폭 기둥용 RAM® 사각 기둥 클램프 베이스 - D 사이즈

Used this to mount my tablet on a heavy equipment post, and the clamp grips tight without slipping. The D-size ball gives plenty of adjustment range, so I can angle the screen exactly where I need it. Feels like it’ll hold up to rough field use.

Ball’s got a nice solid click when it seats, and the clamp handles my 3-inch post without any wobble. Took about two minutes to mount, and the D-size ball locks in tight. Exactly what I needed for a sturdy base.

The clamp grips my 3-inch square post with zero wobble, and the ball joint is rock solid once you tighten it down. Took maybe five minutes to install and it’s held my tablet arm steady through some rough gravel roads.
