Articulating Magic Arm 360° with 1/4” and 3/8” Threads for Camera – Ulanzi TB15

The Ulanzi TB15 is a 360° articulating magic arm equipped with both 1/4” and 3/8” threaded mounts for cameras and accessories. The tool offers continuous rotational adjustment and multi-joint articulation to position lights, monitors, microphones or camera rigs at precise angles. Its combination of standard screw threads and a compact, rigid arm design provides compatibility with a wide range of photographic and video accessories while maintaining stable support during use.

Advantages

The magic arm supports full 360° rotation and multi-angle articulation, allowing fine-tuned positioning without changing mounting hardware. Dual threaded ends (1/4” and 3/8”) make it compatible with most camera accessories and mounts. The construction emphasizes rigidity and reliable grip at the joints to minimize drift or slippage when locked. Its compact footprint and modular thread sizes enable use in both constrained studio setups and on-location shoots where space and flexibility matter.

Suitable for

• Mounting LED lights on camera cages, rigs or booms
• Attaching external monitors or recorders for adjustable viewing angles
• Securing microphones, small reflectors or diffusion panels
• Adding accessories to tripods, stands or stabilizers with 1/4” or 3/8” fittings
• Temporary rigging for photography and video production

How to use

Loosen the central locking mechanism to set the desired angle and rotation of the articulating arm. Position the attached accessory (camera, light, monitor or microphone) to the required orientation and tighten the lock until the arm holds firmly. Use the appropriate thread adapter or screw size if necessary to match the 1/4” or 3/8” mounting point on your device. Check grip stability after tightening before deploying heavy or sensitive equipment.

Usage recommendations

For optimal stability, mount heavier accessories close to the arm’s base and verify all connections before operation. Periodically check joint tension and thread fit, and avoid overtightening to prevent wear on threads and locking surfaces. Use with compatible mounts and follow the weight limits of the supporting tripod, cage or stand.
