The kit includes a rugged aluminum cage and a dedicated phone case. The aluminum cage absorbs shocks, while the case provides daily protection with raised bezels for screen and camera safety. Note: Use only the included or SmallRig-compatible cases. Third-party cases may cause damage.

These allow for attaching accessories such as handles (e.g., 4402B), tripods (e.g., 3935), microphones (e.g., 3468), and video lights (e.g., 3286). Strap mounts (≤2mm) are also included for shoulder or wrist carrying.
