قاعدة RAM® المزدوجة على شكل حرف U بمسامير للسكك الحديدية .75" - 1"

The ball rotates smoothly even under heavy load, and the zinc coating on the u-bolts looks like it will resist rust well. Fits my 7/8" rail perfectly with no play after tightening.

Those double u-bolts cinched down solid on my 1" roll bar with zero wobble, and the zinc coating already looks like it'll shrug off the weather. The 1.5" ball gives a nice wide pivot range for my phone mount. Took about five minutes to install with a socket wrench.

The double u-bolt base fit perfectly around my 7/8-inch rail and feels rock solid once tightened down. I like that both u-bolts are included so I didn't have to hunt for hardware. Exactly what I needed for a sturdy ball mount.
