Selens SAB13-AL RigTree 三角形延伸臂 相機支架

I mounted a 7-inch monitor to this arm and it held steady with zero sag, even during handheld shots. The locking knobs are large enough to tighten by hand without tools, which saved me time on set.

The triangle brace makes this arm rock-solid even when I've got my monitor fully extended off the side. Setup was easy and it locks down tight without any sagging.

Bought this to mount a small field monitor off the side of my rig, and the triangular bracing keeps it perfectly steady even when I swing the camera around. The whole thing feels solid and locks down tight.
