Updated Hardware
The latest Magna specification incorporates revised locking hardware designed to better accommodate the temperature changes experienced inside vehicles.
It is a small engineering change — but exactly the kind of detail that matters when equipment lives on a windscreen through hot days, cold mornings and everyday use.
⚠️ Beware of cheap imitations & disposable magnetic mounts.
Lightweight plastic • weak hardware • little support • little comeback.
Built4it gives you solid materials, proper warranty and UK-based accountability.
Why Magna?
Not every driver needs a giant clamp system. Sometimes you simply want to get in, snap your phone into position and get moving.
Magna gives you the convenience of magnetic mounting while keeping the kind of solid alloy construction and proper support Built4it customers expect.
Built for the Road
The Magna Boulder Holder is designed primarily for standard road use. For sustained heavy vibration, serious off-road use, construction plant or machinery applications, we recommend one of our dedicated clamp-based or heavy-duty Boulder Holder systems.
Different jobs need different tools — Magna is the cleaner, faster option for drivers who value magnetic convenience without dropping down to bargain-bin mounting hardware.
