RAM® Track Ball™ avec base latérale

The t-bolt slides into the groove and locks securely with a satisfying click, so there's zero wobble once it's tightened. I mounted this on an arm for easy repositioning during work, and the quick-turn knob makes adjustments a breeze. Really solid feel for the price.

The 1.5" rubber ball grips the ratchet tooth groove perfectly, so once I snug the t-bolt knob it stays rock solid through a full day of bouncing around in the truck. Setup took maybe two minutes on my existing rail, and the quick-adjust turn is genuinely handy when I swap it between vehicles.

I was relieved the t-bolt mechanism actually locks tight enough to use one-handed while driving. The 1.5” ball responds precisely even with dusty fingers, though it’s still easy to clean with a quick wipe.
