Arkon 1" Ball on Richter plate

SP25MM4P is a versatile adapter that allows you to mount 4-prong iGRIP holders onto mounts accommodating the 25mm (1 inch) ball pattern (including Arkon Robust Mount models and RAM Mounts-sold separately). This includes only the 25mm Swivel Ball to 4-Prong iGRIP Pattern Adapter. (Mounts, holders, and devices sold separately.) Secure the adapter onto any mount accommodating the 25mm (1 inch) ball pattern. Use the SP25MM4P adapter with current Arkon Robust Mount Models RM080AMPS (Heavy-Duty 80mm Suction Mounting Pedestal with 4-Hole AMPS Head), RM2XAMPS (Heavy-Duty 4-Hole AMPS to 4-Hole AMPS Mounting Pedestal), or RM0802T (Heavy-Duty 80mm Suction Pedestal) to make them iGRIP-compatible.
