This component is a RAM Mounts marine-grade aluminum "B" ball with a diamond base.
The diamond base is compatible with Kayalu and RAM Mounts single suction-cup assemblies (KLA-5045). Alternatively, this diamond base is capable of being bolted directly to any planar surface.
Mounting bolts are not included with this base. If you are intending to fasten this base to a RAM Mounts suction-cup (KLA-5045), the two mounting screws are provided with the suction-cup assembly.
