RAM® Pin-Lock™ 安全螺帽 適用於 D 和 E 尺寸臂桿及萬向支架

Finally, a security nut that actually stays tight on my camera rig. The knurled edge gives me just the right grip to lock it down without tools.

After losing a knob on a bumpy trail last month, this security nut fixed the problem—the deep threads in the D/E arm let me torque it down tight without any slippage so far. Fits perfectly on my gimbal bracket too, and the included hex-key slot gives me just the right grip to lock it in place.

The hex key slot on this pin-lock nut makes it much easier to get a tight grip without stripping. It's holding my camera mount steady on bumpy trails, and I appreciate not needing that bulky knob now.
