📦 New Batch. New Colours. Back in Stock.
The Extra-TerraMax Solo and Duo are back in UK stock, now finished in Built4it’s new Black & Orange colourway.
Same heavy-duty Extra-TerraMax architecture. A sharper, more distinctive finish for the latest production batch.
⚠️ When vibration is part of the job, ordinary mounts show their weaknesses.
Lightweight plastics • undersized hardware • movement under leverage • little support when something fails.
Extra-TerraMax is built around alloy structure, vibration control and proper Built4it backup.
🧪 Field Tested — Where Ordinary Mounts Get Punished
Extra-TerraMax has been tested in genuine high-vibration environments including serious mountain-bike riding and heavy construction plant cabins.
Testing has included machinery such as the Hydrema 912G articulated dump truck, Caterpillar D6T dozer, CAT 980 loading shovels, Volvo 360 excavators etc and tracked dump trucks including the Morooka MST-2200VDR.
Those environments bring sustained vibration, jolts, rough terrain and long shifts — exactly the conditions that expose weak joints and lightweight mounting hardware.
Real machines. Real terrain. Real-world testing.
Built for the cab when the cab refuses to stay still.
The Extra-TerraMax is a heavy-duty mounting platform designed for users working around vibration, rough terrain, repetitive shock and long hours behind the controls.
This is not intended to be another lightweight dashboard accessory. Its substantial alloy support structure and Anti-Vibration Silicone Suspension System are designed to help control movement and reduce harsh vibration reaching the mounted device.
Choose Solo when you want the complete Extra-TerraMax system with the smallest mounting footprint, or step up to Duo when additional stability under leverage matters.
Choose Your Extra-TerraMax
Extra-TerraMax Solo — £69.95
Single-suction configuration with a compact footprint and the complete Extra-TerraMax anti-vibration holder system.
Extra-TerraMax Duo — £79.95
Dual-suction configuration with a wider two-point mounting footprint to provide additional stability when leverage, rough terrain or larger devices place greater demands on the system.
- Anti-Vibration Silicone Suspension System — designed to help isolate and absorb vibration before it reaches the phone
- Heavy-Duty Alloy Frame — substantial structural support where rigidity and strength matter
- Solo or Duo Suction Base — choose the mounting footprint that suits your environment
- Industrial Silicone Contact Surfaces — designed for strong adhesion on suitable clean, smooth surfaces
- Adjustable Viewing Position — configure the holder around the cab, vehicle and operator position
- New Black & Orange Finish — refreshed colourway for the latest Extra-TerraMax production batch
- Built for Real Work — plant cabins, trucks, vans, 4x4s, rough roads and demanding off-road applications
Solo vs Duo — straight answer: Solo already gives you the complete Extra-TerraMax holder and suspension system. Duo adds a second suction point to spread the mounting load across a wider footprint and increase stability under leverage when the environment becomes particularly demanding.
🎁 FREE BoulderKey Stand
Every Extra-TerraMax Solo or Duo includes a FREE BoulderKey alloy keychain phone stand.
A compact everyday stand for your phone when the heavy-duty mount stays in the machine.
Built for Real Environments
Extra-TerraMax is aimed at operators and drivers who need more than a road-car phone holder.
Think construction plant, 4x4, off-road, rough access roads, trucks, long shifts and sustained vibration.

Heavy-duty equipment deserves meaningful backup.
Why Extra-TerraMax Costs More Than an Ordinary Phone Mount
Because it isn't designed for an ordinary environment.
Low-cost mounts are generally built around relatively light road use. Extra-TerraMax adds a substantial alloy structure, silicone vibration-control system and heavy-duty mounting hardware for environments where equipment can be subjected to vibration for hours at a time.
If your working day takes place inside machinery worth tens or hundreds of thousands of pounds, the cheapest component available probably shouldn't be the one responsible for holding your phone.

New Black & Orange Colours
The latest Extra-TerraMax batch introduces a new Black & Orange finish for a sharper, more recognisable look across the current production range.
The colour has changed. The heavy-duty Extra-TerraMax purpose has not.

Heavy-duty mounting equipment needs to prove itself in the environment you actually work in. Qualifying Built4it purchases are therefore backed by our 60-Day Money-Back Guarantee, subject to the applicable returns terms.
Installation & Safety: Install only on suitable clean, smooth mounting surfaces. Check suction, adjustment and locking points regularly, particularly in severe vibration environments. Position the device so it does not obstruct visibility, vehicle controls, airbags or the safe operation of machinery. Environmental conditions, surface condition and mounting position can affect suction performance.
