A 1.5 kg rating on a 9.8-inch arm sounds modest until you look at what the clamp gives you: a 1/4"-20 hole and a 3/8"-16 hole through the body, plus 1/4" screws at both ends of the arm. Between those, it holds a monitor, a microphone, a small LED panel, or a phone without an adapter in sight. That spread of fittings is why it is the one we hand to someone who has not decided what they are mounting yet.
The arm itself is single-knob friction: one turn releases both ball ends and the elbow, so you position everything at once and lock it with a twist. We found that quick with a light or a monitor hanging close to the clamp, and fussy with a camera pushed out to the end, where setting one angle nudges the other two. The Neewer ST16C answers that with a toothed elbow, at the cost of a coarser adjustment.
Payload is where we temper expectations. The jaws open wide enough for most desk edges and for round tube, and the rubber cushions grip a painted surface without marking it, but a heavy offset load can still let the ball heads creep after you have tightened them. Keep the weight close in and the arm angled rather than horizontal and it stays put; hang a rig off the far end and you will be re-tightening it.
Folded, it measures 8.66 inches and weighs 333 g, small enough to live in a bag pocket instead of a case, and the aluminum and stainless hardware has the machined feel SmallRig's cages are known for. If you want one arm to cover the widest range of jobs, this is the one that stays in the bag.
Pros
- 1/4"-20 and 3/8"-16 without adapters
- Clamp grips desk edges and round tube
- Folds to 8.66 in and weighs 333 g
Cons
- Ball heads can creep under a heavy offset load
Our default pick: a 9.8-inch arm and clamp that hold a monitor, mic, or small light at almost any angle, and fit nearly every thread you already own.
