صامولة أمان رام® Pin-Lock™ ذات 7 سنون لأذرع المقابس مقاس D وE

The key knob is a nice upgrade over the standard ones—it fits the 1/2"-20 threads perfectly and feels solid when tightening. Swapped out the old knob on my 3.38" mount in under a minute and it hasn't budged since.

I was a bit skeptical about replacing my standard knob, but once I threaded this pin-lock nut onto my D-size arm, it fit perfectly and hasn't loosened at all. The key knob makes adjusting a breeze while keeping everything secure on bumpy roads.

Finally, a security nut that actually fits my D-size RAM mount setup without any wobble. The key knob makes it easy to tighten by hand, and I love that it replaces the old knob while keeping everything locked in place.
