Adam ★★★★★

Used this on a 4-inch rail post and the clamp's jaws grabbed it tight without any wobble, even over rough terrain. The 1.5" ball locks into my device mount solidly. Setup took maybe three minutes with a hex key.

Michael ★★★★★

The rubber ball’s got a satisfying snap when it locks into place, which makes mounting my tablet holder feel super solid. Mounted it on my 4.5-inch post and it hasn’t budged a millimeter, even with my rough handling during a weekend job. Exactly what I needed for a sturdy, no-nonsense setup.

Brian ★★★★★

I needed something sturdy for my thick 4-inch square rail, and this clamp base grabbed it perfectly without any wobble. The rubber ball makes it easy to adjust the angle before tightening everything down.
