The Magna Boulder Holder is Built4it’s low-profile magnetic road mount for drivers who want, a fast one-handed phone placement, strong magnetic retention and substantial mounting hardware without bulky spring-loaded arms or lightweight plastic dashboard clutter.
Designed for cars, vans, trucks, taxis, couriers, commuters and other everyday road vehicles, Magna combines magnetic convenience with a solid alloy mounting platform and full-angle adjustment.
It is MagSafe-compatible for suitable phones and cases, while the supplied 3M-backed metal mounting ring / plate extends compatibility to many non-MagSafe devices and cases.
- MagSafe-Compatible Magnetic Head — quick magnetic attachment for compatible phones and cases
- 3M-Backed Metal Ring / Plate Included — provides a magnetic mounting interface for suitable non-MagSafe devices
- High-Retention Magnetic Grip — designed for secure positioning during normal everyday road driving
- Alloy Body Construction — substantial mounting hardware instead of lightweight plastic architecture
- Updated Locking Hardware — revised hardware better suited to temperature changes experienced inside vehicles
- 360° Adjustment — set portrait, landscape or intermediate viewing positions
- Low-Profile Design — cleaner installation with less obstruction around the mounting area

Why Magna?
Not every driver needs a mechanical clamp wrapped around their phone. Sometimes the priority is simply to get in, dock the phone quickly and get moving.
Magna gives you magnetic convenience without dropping down to disposable mounting hardware: a substantial alloy platform, adjustable positioning, replaceable components and proper Built4it support.
Updated Hardware
The current Magna specification incorporates revised locking hardware designed to better accommodate the temperature changes experienced inside vehicles.
It may sound like a small engineering change, but equipment mounted against vehicle glass can experience considerable temperature variation between cold mornings and hot summer interiors.
🛣️ Magna Magnetic — Built for the Road
The Magna Boulder Holder's magnetic configuration is designed primarily for normal road use.
It is ideal for cars, vans, trucks, taxis, couriers and professional drivers who value rapid magnetic mounting and removal.
For sustained heavy vibration, construction plant, severe off-road use or extreme 4x4 environments, we recommend a Built4it mounting system using positive mechanical device retention rather than magnetic-only retention.
Different jobs need different tools — Magna is our fast, clean road-use solution.
Coming Soon
Magna Boulder FoneTab Expansion
The Magna Boulder platform is becoming modular. An incoming FoneTab Phone & Tablet Clamp will provide a second, separate mechanical device-retention option for the same mounting platform.
The Magnetic Phone Head and FoneTab Phone & Tablet Clamp are separate interchangeable heads — they are not combined into one holder.
Magna will remain the fast magnetic road-use configuration, while FoneTab will extend the platform into mechanical phone and tablet retention for more demanding environments.
🔄 One Platform. Different Tools for Different Jobs.
The modular architecture means the complete mounting system does not need to be replaced simply because your device-retention requirements change.
Choose the Magnetic Phone Head when speed and convenience matter, or the separate FoneTab mechanical clamp when positive mechanical retention and wider phone/tablet compatibility are required.
⚡ Why Add the 200W Power Kit?
A serious vehicle mount is often only half the setup. Navigation, communications, music, work apps and long journeys can place heavy demands on your devices.
The Power Kit combines the Magna Boulder Holder with the upgraded Power Trip 200W alloy car charger and Cable Construct, creating a complete mounting and in-vehicle charging package.
The wall charger is not currently included. Built4it is evaluating the next mains-charging unit before introducing a new wall-power option.
⚠️ Cheap magnetic mounts are easy to find.
Lightweight hardware • disposable construction • little support • little comeback.
Built4it gives you substantial hardware, proper warranty and UK-based accountability.
