How to use

Open the spring-loaded clamp and place the smartphone between the jaws, ensuring the device is centered and the clamp does not cover essential buttons or the camera lens. Attach the holder to a tripod, selfie stick or rig using the standard screw thread and tighten until secure. Adjust the phone position and angle on the tripod or accessory to obtain the desired framing; check stability before recording or streaming.

Usage recommendations

For best results, verify that the clamp is seated on the phone frame or case rather than over fragile screens or glass edges. Use with compatible tripods and mounts rated for your device weight, and periodically inspect the clamp and attachment threads for wear to maintain stable performance.
