Manfrotto 131DDB 四雲台用三腳架配件臂（黑色）

This arm screws right onto my tripod's 3/8″ thread and the 90° angle makes it easy to balance four heads without them knocking into each other. It's solid and feels much sturdier than I expected for the size.

I needed to mount four lights on one stand for a small interview setup, and this arm made it simple with its perpendicular 90° side mounts. The threads gripped my column perfectly on the first try, holding all four heads securely without any wobble.

The threading on the 3/8″ column mount is precise, so it screwed on without any wobble. I’ve got two heads on the side arm and another two at the perpendicular angle, and everything stays rock-solid during a full shoot.
