Model RMSMAMPS2517 Robust 4-Hole AMPS Drilled Base (Aluminum) Mount is part of Arkon’s Robust Mount Series. 

It is compatible with existing 17mm ball pedestals, holders, and cradles, and mounts to car dashboards and consoles as well as walls or other solid flat surfaces with screws (not included) using the 4-Hole AMPS drilled base mounting pattern. 

The mount is compatible with 17mm ball holders and adapters, including Arkon’s Mobile Grip 2 and Mobile Grip 5 Universal Phone Holders as well as other third-party 17mm ball compatible holders. The mount is also compatible with Garmin GPS utilizing the 17mm ball mount pattern. 
This mount includes only the heavy-duty 4-Hole AMPS mount with 17mm ball head. Holders and adapters sold separately. 

The AMPS pattern consists of four holes located in a rectangular pattern spaced at 30.17mm x 38.05mm (measured as the center-to-center distance between holes). 

This tough, low-vibration composite mount measures 4.5 inches high from end to end. 
The mount arm swivels on both the top and the bottom, providing 360-degree rotation and the ultimate flexibility in positioning the device at any angle. 
The mount can also be drilled directly into the dash or console of your vehicle or work truck.
