Mount Adapter Ulanzi SB9112 — 1/4" Thread Foot Adapter for DJI Action 3/4 (ISO-Compatible)

Ulanzi SB9112 is a mount adapter that converts the proprietary mount of DJI Action 3 and DJI Action 4 cameras to a standard 1/4" threaded foot. The ISO-compatible adapter creates a mechanical interface that allows these action cameras to be attached directly to tripods, articulating arms, cages and other photographic or video accessories with a 1/4" socket. The design focuses on a compact footprint and secure connection for stable shooting and equipment integration.

Advantages

The adapter offers a secure, ISO-compatible 1/4" threaded interface that enables use of a wide range of existing accessories. It reduces the need for additional adapters or bespoke mounts by providing a direct mechanical connection between DJI Action 3/4 cameras and standard 1/4" fixtures. The compact form factor maintains a low profile on the camera and supports quick attachment and removal while preserving stable alignment.

Suitable for

• Mounting DJI Action 3 or Action 4 cameras on tripods and monopods with 1/4" screws
• Attaching cameras to cages, rigs and stabilizer plates that accept 1/4" mounts
• Integrating action cameras into multi-camera setups and accessory ecosystems
• Using with articulating arms, extension poles and clamps with 1/4" sockets

• Thread type: Standard 1/4" male threaded foot (ISO-compatible)
• Mechanical interface: Converts proprietary camera mount to 1/4" accessory interface
• Form factor: Compact, low-profile adapter suitable for on-camera use

How to use

Align the adapter with the camera’s mounting point and press or slide it into place following the camera’s mount engagement method. Once seated, secure the connection according to the camera’s mounting mechanism. Thread the 1/4" screw of the tripod or accessory into the adapter’s 1/4" threaded foot and tighten until the camera is held firmly. Confirm the camera angle and stability before operating. To remove, reverse the attachment steps, unthread the accessory and disengage the adapter from the camera mount.

Usage recommendations

Use a short, firm thread engagement on the 1/4" screw to avoid over-tightening and protect both the adapter and accessory threads. Check the combined load capacity of your accessory and camera configuration before use; when mounting on long arms or extension poles, verify balance and secure secondary safety measures such as straps or clamps if needed.
