The extremely versatile, the new ST-16 FOLDABLE METAL SMARTPHONE CLIP from Ulanzi is designed to attach to an (optional) tripod via one of three ways. It has a 1/4"-20 mounting hole, a 3/8" mounting hole, and the bottom plate is compatible with Arca-style quick release plates. The base can also be used on flat surfaces without the need of a tripod.
The mount can hold a smartphone in either vertical or horizontal orientation. The adjustable, silicone-padded grips support phones from 2.2" to 3.4" wide. For additional functionality, you can use the hidden cold shoes that are milled into each end of the mount. You can attach items like an LED light or external microphone. When finished, the mount folds to a more compact and storage-friendly size.
