Size: RegularThe popular spring-loaded X-Grip phone holder features an 'X' design that expands and contracts to provide a perfect fit for your device even if it's in a case. Made of high-strength composite and stainless steel, the X-Grip phone holder is compatible with a wide variety of double socket arms and mounting bases. This version of the X-Grip fits phones ranging from 1.87" to 3.25" in width and keeps your device completely functional and accessible. No matter what double socket arm and mounting base you pair the X-Grip with, ball and socket technology allows for near-infinite adjustability to achieve the ideal viewing angle while also extending the life of your phone by providing shock and vibration damping. For outdoor applications like being used as a motorcycle phone mount the X-Grip includes a device tether that is recommended for added security and peace of mind.
