Our Boulder Holder mounts are built to last — solid materials, real warranty, real accountability.
🧪 Field Tested — Not Just “Amazon Strong”
This mount style has been tested in real-world conditions including serious mountain bike riding and heavy construction plant cabins — including ruthless machines with only suspended seats like the Hydrema 912G, bull dozers like the Caterpillar D6T, loading shovels, 360 excavators, and tracked dumpers such as the Morooka MST-2200VDR — these machines have no ride comforts like suspension.
So, if it can stay put in those environments, it’ll handle daily road driving like it’s nothing.
The flagship mount. Built for extreme vibration and heavy-duty use.
The Ultra Boulder Holder is our most heavy-duty mount — built for industrial use, off-road vehicles, plant machinery and high vibration environments, and anyone who’s sick of mounts that creep, wobble, or eject your phone onto the floor under your foot. If your phone costs £1,000+, protect it like it does.
Our most heavy-duty phone mount — built for extreme environments where others fail.
✅ Suction Options (select using the variant dropdown)
Ultra (Single Suction): Clean install, strong hold — ideal for most vehicles.
Ultra Duo (Dual Suction): Added surface contact for improved stability when device weight/leverage increases.
- Hybrid Alloy Clamp — locks like steel on potholes, tracks and machinery.
- Anti-Vibration Arms — cuts shake for stable navigation & filming.
- One-Twist Lock — fast to mount, won’t rattle loose.
- Industrial Silicone Contact — strong seal on smooth flat surfaces.
- Built4it-grade materials — alloy + silicone + proper build quality.
Single vs Dual (straight talk): Single suction is seriously strong. Dual suction is about stability under leverage — spreading load and reducing movement when setups get heavier or longer.
