Disposable plastic • no warranty • no support • no comeback.
Our Boulder Holder mounts are built to last — solid materials, real warranty, real accountability.
🧪 Field Tested — Not Just “Amazon Strong”
Tested in real-world conditions including mountain biking and heavy construction plant cabins — machines like the Hydrema 912G, dozers like the Caterpillar D6T, loading shovels, 360 excavators, and tracked dumpers such as the Morooka MST-2200VDR.
No suspension. Constant vibration. Long shifts.
If it can stay put in those environments, daily road driving is light work.
Same ruthless mount. Choose your base.
The Extra-TerraMax platform is built for environments where vibration and long shifts expose weak mounts. You’re not buying a “dashboard accessory” — you’re buying a mount designed to hold position.
A rugged suction phone mount built for high vibration and real-world use.
✅ Suction Options (select using the variant dropdown)
Extra-TerraMax (Single Suction): Clean footprint, fast install, seriously strong for most setups.
Extra-TerraMax Duo (Dual Suction): Added surface contact for extra stability under leverage (rougher environments, heavier phones).
- Anti-Vibration Silicone Suspension System — absorbs shake before it hits your phone.
- Heavy-Duty Alloy Frame — no flex, no creep, no fatigue.
- Industrial Silicone Contact — high-friction seal on smooth flat surfaces.
- Built for real work — trucks, vans, 4x4s, plant cabins and long hauls.
Single vs Dual (straight talk): Single suction is already a beast. Dual suction is about stability under leverage — spreading load and reducing movement when the job gets rough.
Built for real environments
Designed for harsh daily use — not showroom dashboards. If your mount creeps, your attention wanders. This is built to stay put.

Why paying less costs more
Cheap mounts rely on plastic arms and undersized suction cups. Under vibration, they creep, flex, and eventually fail. Extra-TerraMax is engineered to hold position for the whole shift — not just the first mile.
