Category: Camera Rigs

The SmallRig 3874 is a compact magic arm with two ball heads, sized for mounting lightweight accessories — small monitors, microphones, LED panels — to a camera cage or rig. One head uses a 1/4"-20 screw, the other uses an ARRI locating thread, so it attaches to a wide range of cinema and mirrorless accessories without an extra adapter.

Articulation lets you get off-axis where a fixed cold shoe can't reach.

Available from Filmgear Canada, with Canada-wide shipping.

Customer Reviews (5.0 / 5 · 5 reviews)

Alexander ★★★★★

Got this for my field monitor and the ARRI locating screw kept it securely locked in place even when I was moving around a lot. The build feels solid and the ball joints hold their position firmly without any slipping.

Penelope Z. ★★★★★

The dual ball heads let me position my LED panel exactly where I need it, and the locking mechanism holds tight even when I bump the rig. It's surprisingly sturdy for such a compact arm.

Joshua D. ★★★★★

Used it to hold a small monitor on my cage for a weekend shoot, and the ARRI locating screw kept everything rock-solid even when I swung the rig around. The compact size is perfect for tight setups where a full arm would be overkill.
