Securely mount your smartphone with the Mobile Phone L-Clamp with Dovetail Jaw and Pocket Stand from Really Right Stuff. This mount fits devices 2.3 to 3.4" wide and has two 1/4"-20 standard threaded holes for mounting on tripods, monopods, and more. The mount adjusts using a knob and a custom hex key that is secured within the clamp with a pair of rare earth magnets while a knob locks the phone in place. The L-Clamp ensures that your device can be mounted in either landscape or portrait orientation, and angled jaws hold your device in place and are lined with firm rubber. A 1.5" quick-release dovetail jaw lets you directly mount your device to compatible ball heads and other devices. The included Pocket Stand folds down with a click and attaches to the back of your clamp with a ball joint and its own tightening knob. The stand has its own 1/4"-20 threaded hole for mounting to tripods.
