The RM079AMPS sticky suction windshield or dash mount is part of Arkon's Robust Mount Series and is compatible with devices having an industry-standard 4-Hole AMPS pattern, including cameras, GPS devices, satellite radios, or audio/video receivers. The 4-Hole AMPS mount pattern consists of four holes located in a rectangular pattern spaced at 30.17mm by 38.05mm (measured as the center-to-center distance between holes). This 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 80mm Sticky Suction Mount with 4-Hole AMPS Head. This tough, low-vibration mount measures approximately 4.5 inches high from the suction base to the top of the pedestal (holder not included), and is made of a combination of plastic and glass fiber. The 80mm sticky suction base uses a combination of polyurethane gel and suction to provide a maximum surface bond in all climates. To restore the suction, just rinse the pad with a mild liquid soap and warm water then air dry. The arm of the mount swivels on both the top and the bottom, providing 360-degree rotation and the ultimate flexibility in positioning the device at any angle.
