مقبض أمان RAM® Pin-Lock™ ذو 5 دبابيس للأذرع من الفئة C والأذرع المتأرجحة

The threaded security knob fit perfectly on my RAM mount's C size arm, and the key mechanism feels sturdy when locking it down. It's nice having a simple way to deter casual theft without needing a full tool set.

Finally, a knob that actually stays put. The 5/16"-18 threading fits my C size arm mount perfectly, and the key lock gives me peace of mind leaving my gear on the truck rack.

I've been using this security knob on my C size swing arm mount for about a week, and the 5-pin locking mechanism feels much sturdier than the old plastic knob it replaced. It fits perfectly on the 1.5" diameter arm and the keyed lock gives me peace of mind when I leave my gear in the truck.
