Ram Mounts RAMB166UN7 X-Grip Phone Mount with Twist-Lock Suction Cup

The Ram Mounts RAM-B-166-UN7 is a complete windshield phone mounting solution, bundling a 3.3" diameter Twist-Lock™ suction cup base, a standard-length double socket arm, and the popular spring-loaded X-Grip® universal phone cradle. The suction cup base delivers a strong, reliable hold on glass and non-porous plastic surfaces, making it well-suited for vehicle windshields and dashboards.

The X-Grip® cradle features a four-point grip design that expands and contracts to accommodate a wide range of smartphone sizes — fitting devices from 1.875" to 3.25" in width — including phones in cases, sleeves, or skins. Unlike padded cradles, the open X design keeps all ports, buttons, and screens fully accessible at all times.

• 3.3" diameter Twist-Lock™ suction cup base — strong hold on glass and non-porous surfaces

• Spring-loaded X-Grip® cradle fits phones 1.875" to 3.25" wide
• Open four-leg cradle design — keeps device fully functional and accessible
