SmallRig 15mm 硬質陽極氧化鋁導管一對（各 12 吋）

The inner M12 threads on each end make attaching accessories straightforward, and the 12-inch length gives plenty of spacing on my rig. The hard anodized surface has held up well against a few knocks so far, no scratches or wear.

The inner M12 threads at both ends make these a breeze to lock into my rig, and the hard anodized finish feels rock solid compared to cheaper rods I've handled. They're exactly 12 inches, so they fit my setup without any awkward overhang.

Swapped out my old plastic rods for these aluminum ones, and the hard anodized finish already feels way more durable. The inner M12 threads at both ends made attaching my follow focus a breeze. Exactly what I needed for a solid 12-inch rail setup.
