Made of high-strength composite and stainless steel, the RAM® X-Grip® phone holder is compatible with a wide variety of RAM® double socket arms and mounting bases. No matter what double socket arm and mounting base you pair the RAM® RAM-HOL-UN7BU X-Grip® with, RAM® 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.
