The RM2XCMAMPS25 4-Hole AMPS drill base mount is part of Arkon's Robust Mount Series. It features a metal AMPS drill mount base as well as a metal AMPS head for extra stability for commercial vehicle use. This mount measures approximately 7.25 inches high from end to end, and the mount shaft arm is made of metal. The mount's circular AMPS adapters provide flexibility when mounting in an area where a square adapter won't work. The mount can be drilled into solid, flat surfaces, such as car dashboards or consoles as well as walls, tables, and workbenches. The mount is compatible with devices having a 4-Hole AMPS pattern, including cameras, GPS devices, or satellite radios. The mount is also compatible with Zebra Models QLn420, ZQ510, and ZQ520 mobile printers. 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 mount with metal 4-Hole AMPS drill base and head. The mount's shaft arm provides double adjustment points, providing 360-degree rotation and the ultimate flexibility in positioning the device at any angle.
