The RM0792TWD windshield or dash sticky suction mounting pedestal is part of Arkon's Robust Mount Series. It replaces or upgrades an existing pedestal and is compatible with Arkon's Dual-T pattern compatible universal smartphone and tablet holders (sold separately), including the Slim-Grip Ultra Universal Smartphone and Midsize Tablet Holder (SM060-2), Slim-Grip Universal Tablet Holder (TAB001), and Mega Grip Universal Smartphone Holder (SM040-2). This mount includes only the Heavy-Duty 80mm Sticky Suction Mounting Pedestal with a Dual-T Head and optional adhesive dash disk. (Holders sold separately.) The suction mounting pedestal is ideal for car windshields, dashboards or other flat or slightly textured surfaces. This tough, low vibration pedestal measures approximately 6.5 inches high from the bottom of the mount base to the top of the pedestal (not including holder), and is made of a combination of plastic and glass fiber. The arm of the pedestal swivels on both the top and the bottom, providing 360-degree rotation and the ultimate flexibility in positioning the smartphone or tablet at any angle. 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. In order to prevent permanent indentation marks on soft vinyl, leather, or similar dash surfaces, Arkon recommends using the included 3M adhesive dash mounting disk.
