The mount is compatible with devices having a 4-Hole AMPS pattern, including cameras, GPS devices, or satellite radios. 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 mount is also ideal for mobile radio holders, housings, and other devices used by public safety, construction, and utility applications. This package includes only the heavy-duty mounting pedestal with metal 4-Hole AMPS drill base and head. This mount measures approximately 7 inches high from end to end, and the mount shaft is made of metal. The mount arm swivels on both the top and the bottom, providing double 360-degree rotation and the ultimate flexibility in positioning the device at any angle.
