RMSMAMPS2522 Robust 4-Hole AMPS Drilled Base (Aluminum) Mount is part of our custom Arkon Robust Mount Series. 

It is compatible with existing 22mm 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 22mm ball holders and adapters as well as other third-party 22mm ball compatible holders. 

The mount is also compatible with Garmin GPS utilizing the 22mm ball mount pattern. 
This mount includes only the heavy-duty 4-Hole AMPS mount with 22mm 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 approx. 5.5 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. 

(Warning: Use caution and consult a mobile install professional to avoid drilling into any sensitive vehicle components.)
