RAM® X-Grip® Large Phone Mount with Diamond Base

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. 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. The included diamond ball base features the industry-standard AMPS hole pattern, while RAM® ball and socket technology allow for near-infinite adjustability to achieve the ideal viewing angle – and helps to extend 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.
