The suction cup twist lock base contains a standard RAM double hole diamond shaped end. The 3.3″ diameter suction cup is designed to have an extra strong hold on any smooth non-porous surface, but for best results mount the suction cup on a glass surface. The diamond shaped end has two holes 1.912″ from center to center. This will connect to RAM-B-238 Diamond Plates Series, the universal industry standard AMPS hole pattern or directly to the back of the RAM Composite HOL Cradles.
