The RAM X-Grip Large Phone Mount with Vibe-Safe and Small Tough-Claw from RAM MOUNTS provides a straight forward mount that clamps around handles and rails 1 to 1.6' in diameter. With universal compatibility, as long as your smartphone is 1.75 to 4.5' in width and under 0.875' in depth, it will work with this holder no matter the brand. Rotate between portrait and landscape modes by loosening the center screw for more viewing options. RAM MOUNTS' Vibe-Safe is an accessory designed to protect devices from a wide range of vibration frequencies, making this mount effective when used in vehicles. An optional tether is included for added security during outdoor applications.
