Arkon 20mm Ball to 25mm Ball Adapter

The SP20MM25 is a handy adapter that steps a 20mm mounting pattern up to a 25mm (1 inch) mounting pattern (sold separately). Supplied on its own as the 20mm Ball to 25mm Ball Adapter only — mounts, holders and devices are sold separately. Fit it to any mount that uses the 20mm ball pattern, including Arkon Heavy-Duty Mounts like the Multi-Angle Drill-Base Mounting Pedestal with 8” Adjustable Arm (Model HD006), the Heavy-Duty Clamp Mounting Pedestal with 10” Adjustable Arm (Model HD004) or the Heavy-Duty Seat Rail Mounting Pedestal with 22” Adjustable Arm (Model HD001), and that mount will then work with Arkon Robust Mounts or any other holder or device using a 25mm (1 inch) mounting pattern.
