Description
Mount your phone securely and access it easily with the RAM® X-Grip® Large Phone Mount with Long Arm & Twist-Lock™ Suction Cup (RAM-B-166-C-UN10U). Designed for use on vehicle windshields and other smooth, non-porous surfaces, this premium mount combines rugged materials with a flexible, adjustable design for maximum convenience and reliability.
The 3.3” RAM® Twist-Lock™ suction base creates a rock-solid hold on glass or dash disks, while the long-length double socket arm gives you extended reach and adjustable positioning for perfect viewing angles. The RAM® X-Grip® cradle, featuring its signature spring-loaded “X” design, expands to securely fit large phones (1.75"–4.5" wide) — even with a case on.
Engineered from marine-grade aluminum, stainless steel, and high-strength composite, this mount is built to handle vibration, heat, and daily use without wear. The ball-and-socket system allows near-infinite adjustability, giving you easy rotation for portrait or landscape orientation. For added confidence on the road or trail, an optional device tether is included to keep your phone extra secure in rugged environments.
Whether you’re driving, working, or navigating in the field, the RAM® X-Grip® with Long Arm Suction Mount keeps your device stable, visible, and ready when you need it.
