AMPS Drill Base Mount | 7" Modular Arm | Phone/GPS Holder | 20mm Ball System

4 reviews

ALL METAL DRILL BASE - The metal drill base has a 20 mm hardened aluminum ball that connects to our arm. Great for drilling into the dashboard of trucks, municipal vehicles, work vans, etc. Be sure to consult your vehicle manufacturer to ensure that you're drilling into a safe area.

DEVICE COMPATIBILITY - The automotive grade ABS cradle is designed for an extremely strong hold. Its design requires two hands to insert and remove the phone. Steel springs and rods provide the best gripping strength. This will comfortably and securely hold all devices up to 3.75” Wide. This includes all iPhones including Plus Sized Devices and many of the large rugged cases.

MOUNTING POSITION VERSATILITY - Between the suction cup and the cradle is our 7" modular arm with a hardened aluminum ball connector at each end allowing two connectors a full range of motion. Additional elbow joint in the middle provides even more positions. This metal arm configuration allows easy repositioning, along with a ROCK SOLID, vibration free hold.

Uri L. (Tampa, US)

Wow, no words, worth every penny that I spent!!!, I installed it on my Volvo VNL 760, right o. The Incab fusebox cover, I was skeptical at first, but I assure you this mounts are amazing!

Kareem H.

great buy, inner lining could stay sticky better

Excavator (San Francisco, US)
Great for excavators

I have these mounted in each of my excavators, will take extra thick battery phone cases and hold them well even while excavating. Great adjustability!

FastRaptor2019 (Sierra Vista, US)
Sturdy and well Made

Added this to my 2019 Ford Raptor and looks great, holds my iPhone 11 Pro with no problems and doesn't budge during off-road bumps. Highly recommend for anyone who is looking for a off-road worthy phone mount. Would have been nice if it came with screws to mount it.
