RMSMET2XCM is a metal 4-Hole AMPS Mount that's part of Arkon's Robust Mount Series. The mount includes a metal Robust shaft arm, with circular metal 4-Hole AMPS adapters connected to either end to create a versatile, double-ball swivel drilled base mount that provides flexibility in positioning. RMSMET2XCM is compatible with devices, holders, cradles, and other components having a 4-Hole AMPS pattern. This tough mount is ideal for mobile radio holders, housings, and other devices used by public safety, construction, and utility applications. It is compatible with Arkon's Slim-Grip Universal Tablet Holder (Model TAB001-AMPS), Universal Metal Locking Tablet Holder (Model TAB004KL-B), Universal Locking Tablet Holder (Model TAB005KL), and other holders or cradles having a 4-Hole AMPS pattern. This mount is also compatible with cameras, GPS devices, or satellite radios having a 4-Hole AMPS pattern. The mount measures 4 inches tall from end to end, which is ideal for tight areas. Circular metal 4-Hole AMPS adapters at either end of the metal Robust shaft provide added stability. The mount can be drilled into solid, flat surfaces, such as car dashboards or consoles, as well as to walls, tables, and workbenches. The 4-Hole AMPS drilled-base 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 package includes only the heavy-duty metal 4-Hole AMPS mount. No holders are included.
