Ulanzi MA51 QuickClip Phone Clamp

The Ulanzi MA51 QuickClip Phone Clamp is a metal quick-release clamp for smartphones featuring a UKA base, compatibility with the F38 system, 180° tilt, 360° rotation, and two cold shoe mounts for accessories. It holds phones approximately 66–89 mm wide and is suitable for vlogging, livestreaming, and mobile photo/video setups.

The MA51 is a versatile phone mount for creators who want to quickly switch between a tripod, rig, cage, or other mount. The UKA quick-release base speeds up attachment and removal while allowing integration with compatible Ulanzi/F38 systems.

The clamp securely holds phones with a width of 2.6–3.5" / 66–88.9 mm. Thanks to its metal construction, it feels more robust than standard plastic mounts and is suitable even for more demanding mobile filming.

180° tilt and 360° rotation allow you to position the phone horizontally or vertically and quickly fine-tune the shooting angle. Two cold shoe mounts let you attach a small LED light, microphone, or other accessories.

The bottom 1/4"-20 thread with ARRI positioning holes expands mounting options on tripods, arms, and other rigging components. The MA51 can thus serve as the foundation for a compact mobile production setup.
