With the SIRUI smartphone clamp, you can easily and securely mount your smartphone on a tripod. The rubberised clamp jaws protect the phone and ensure a secure hold at the same time. Thanks to its 1/4 inch thread, it will fit any tripod or tripod head with a 1/4 inch screw thread. Using the tension lock on the back, the clamp can be opened and the smartphone removed. The holder can be used for a variety of applications: long exposure shots, videos, self-portraits, time lapses and much more.
