The popular spring-loaded RAM® 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 powder-coated, marine-grade aluminum, stainless steel components, and high-strength composite, the RAM® X-Grip® phone holder is compatible with a wide variety of RAM® double socket arms and mounting bases. This large version of the RAM® X-Grip® fits phones ranging from 1.75″ to 4.5″ in width and keeps your device completely functional and accessible. No matter what double socket arm and mounting base you pair the RAM® 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. For outdoor applications – like being used as a motorcycle phone mount – the RAM® X-Grip® includes a device tether that is recommended for added security and peace of mind.
