SP25MMCAM is compatible with cameras having the 1/4"-20 mounting pattern, and fits onto mounts accommodating the 25mm ball pattern (including Arkon Robust Mount models and RAM Mounts-sold separately). This package includes only the 25mm Swivel Ball to 1/4"-20 Camera Mounting Bolt Adapter. (Mounts, holders, and devices sold separately.) Secure the adapter onto any mount accommodating the 25mm ball pattern, then screw the camera on using the 1/4"-20 mounting bolt. Use the SP25MMCAM 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 camera-compatible. Or, for complete heavy-duty camera mounting solutions that include SP25MMCAM, Arkon recommends Robust Mount models RM0801420 (Heavy-Duty Camera Suction Mount) or RMAMPS1420 (Heavy-Duty 4-Hole AMPS Wall Mount for Cameras).
