Rugged Ridge X-Clamp in Black 1.25-2.0" Pair Reviews
They don't tell you which layout is for the specific tube diameters, and it can result in a lot of trial and error to get the best fit.
They hold nicely, even on an angle for the mount point. I used mine to hold a light bar low, and the feet angling forwards of the tube the clamps are on.
