The RM2X803250 triple Robust double windshield suction mount is part of Arkon's Robust Mount Series. This mount includes double 80mm windshield suction bases, with triple Robust shafts. This mount features Model APT325MM, our unique T-shaped adapter that connects the three Robust shafts for extra strength in tough environments. This heavy-duty 17mm ball compatible mount is ideal for vehicles with large windshields. The suction bases lock into place on the windshield with one-touch levers and work well in all climates. Each Robust Mount shaft provides double adjustment points for positioning of the mount and your 17mm ball-compatible device.
