Medium Arm for Perfect Positioning
The included medium-length B-size double socket arm offers the perfect balance between reach and stability. You can easily adjust your phone’s position — tilt it toward you, rotate it 360°, or shift it for optimal viewing.
Thanks to RAM Mounts’ patented ball-and-socket design, you get smooth, infinite adjustability while keeping your device locked in place under heavy vibration or bumps.
Built for the Harshest Conditions
Unlike cheap plastic mounts, the RAM-B-138-UN10 X-Grip is built using marine-grade aluminum, high-strength composite, and stainless-steel hardware. It’s corrosion-resistant, weatherproof, and ready for anything — whether mounted on a motorcycle handlebar, off-road buggy, or airplane cockpit.
Every component is over-engineered for performance, ensuring long life and consistent reliability, even in extreme environments.
