Manfrotto 3/8インチねじ込み式 フリクションアーム用回り止め付き

Finally, a 3/8 inch thread adapter that actually stays put when I tweak the friction arm. No more creeping or loosening during a shoot, it's exactly what I needed.

The anti-rotation design on this fitting locks into my friction arm perfectly, no more slipping during adjustments. It’s a small upgrade that makes a huge difference for rig stability.

Finally, a 3/8 inch thread that doesn’t spin loose when I tighten my friction arm onto a stand—that anti-rotation design makes setup much less frustrating. Snap it on and it holds solid, even with a heavy monitor attached.
