James ★★★★★

I’ve been using this on a square tube and the octagon clamp grips it really securely without any slipping. The 2.25" ball system makes it easy to adjust the angle just where I need it. Installation was straightforward and it feels solidly built.

Avery U. ★★★★★

The clamp grips my round rail perfectly without any wobble, and the 2.25" ball socket holds my device steady even on bumpy roads. Installation took about five minutes with the included hardware, which was a pleasant surprise.

Joshua P. ★★★★★

Installed this on my boat’s RAM mount system and the octagon clamp grips the rail way tighter than my old round clamp ever did. The 2.25" ball holds my GPS firmly even through choppy water.
