RAM® Swing Arm Knob

The brass-threaded insert on this knob is a nice touch—feels solid when I tighten it down on my swing arm setup. It threads in smoothly and keeps my tablet from wobbling, even on rough trails. Just what I needed for a secure hold.

I've swapped these knobs between a few swing arm setups and the 3/8"-16 threading holds up great, no stripped threads or wobble even after constant tightening. The grip is solid enough to crank down with one hand, which makes adjusting on the fly way less of a chore.

This knob’s thread matched the swing arm perfectly, and the textured grip makes adjustments easy even with sweaty hands. Only wish it came in a slightly darker black to match my gear better.
