FPN Adjustable 1" Ball Phone Holder for 4.7–7" Smartphones — 3.54" Arm, Vibration Dampener, Quick 1s Lock & Release

The FPN Adjustable 1" Ball Phone Holder with a 3.54" medium arm is a universal, camera-safe smartphone mount that fits 4.7–7" devices and attaches to standard 1" ball systems for secure, vibration-reduced use.

This compact mounting solution pairs a quick one-second lock & release clamp with a rubber-coated 1" ball joint and a built-in vibration dampener. Designed to integrate with RAM-style hardware and other 1" ball systems, the holder keeps your phone accessible, camera-unobstructed, and protected from road shock while offering full 360° rotation and angle control.

How quickly can I mount and remove my phone?

FPN’s clamp uses a fast-action lock and release that secures your device in one motion and ejects it with a single press. The adjustment knob lets you set the clamp width for a consistent one-handed operation, minimizing fumbling while on the move.

• One-second push-to-lock and button-eject release.
• Adjustable knob for custom clamp tension and repeatable fit.
• Wide opening accommodates phones with most cases (up to 0.6" thickness).

Will this mount protect my phone’s camera during travel?

Yes — the integrated vibration dampener reduces transmitted road and engine vibrations that can stress delicate camera stabilization systems. The open-frame clamp avoids covering the lens or sensors, so you can shoot or use Face ID without repositioning the mount.

• Vibration dampening element absorbs shock to protect OIS components.
• Open design keeps camera lenses, ports, and sensors unobstructed.
• Stable clamp minimizes movement for clearer in-vehicle video capture.

Is it compatible with my existing RAM or 1" ball accessories?

This holder uses a standard 1" (25 mm) ball pattern, making it compatible with RAM B-size mounts and most other 1" ball-based hardware. The package includes a 1" to 17 mm ball adapter and a 3.54" double-socket arm for immediate use or integration into a larger mounting setup.

• Standard 1" ball interface fits many aftermarket bases and arms.
• Included adapter expands compatibility with different mount sizes.
• 3.54" double-socket arm provides flexible positioning options.

How adjustable and secure is the viewing angle?

The rubber-coated ball joint rotates freely for 360° positioning and locks firmly with the tightening knob, delivering zero-wobble stability when set. Whether you need landscape navigation or portrait video calls, the mount holds the chosen angle reliably.

• 360° rotation for portrait or landscape orientation.
• Rubber coating increases friction for steadier holds.
• Locking knob enables fine angle adjustments and firm fixation.

Who this is for: The FPN Adjustable 1" Ball Phone Holder is aimed at commuters, delivery drivers, content creators, and anyone who needs a dependable, camera-friendly mount that integrates with existing 1" ball systems. It’s well suited for people who use navigation, capture video while driving, or want a fast one-handed mount that protects phone optics and remains compatible with RAM-style hardware.
