RAM Mounts X-Grip Large Phone Mount with Diamond Base - Secure Hold

Our review of the RAM Mounts X-Grip Large Phone Mount with Diamond Base finds it ideal for drivers and outdoor users who need a dependable, rugged phone mounting solution. The single biggest reason to consider this mount is its combination of a spring-loaded X design that grips large phones without obscuring the screen and a diamond ball base that delivers near-infinite adjustability, so the device stays readable and reachable on rough roads or boats.

Key Features

• Spring-loaded X design: Provides strong, visible holding power for large phones while keeping the screen and ports accessible.
• Diamond ball base: Uses the universal AMPS hole pattern to fit a wide range of mounting locations and accessories.
• Ball and socket adjustability: Lets you position the phone at virtually any angle for optimal viewing and glare reduction.
• Rugged construction: Built from powder-coated marine-grade aluminum, stainless steel, and high-strength composite for long-term durability in harsh environments.
• Optional tether included: Adds peace of mind during rugged use by preventing accidental drops in extreme conditions.
• Lifetime warranty: Backed by the manufacturer's lifetime warranty, offering long-term support for the mount.

Who It's For

This mount suits boaters, off-road drivers, and commuters who demand a secure hold for large phones and frequent angle adjustments. Anyone who needs a mount that resists corrosion and stands up to rough terrain will benefit from its marine-grade materials and solid hardware.

Those who only need a minimalist or ultra-compact mount for small phones, or who prefer suction-style placement on glass, should look elsewhere; this product is best for hard-mounted installations using the AMPS pattern and for users who value durability and security over smallest footprint.
