The locking 3.25" Rubber Suction Cup Base has a standard RAM double hole diamond shaped end. The suction cup is designed to have an extra strong hold on any smooth non-porous surface, but for best result, 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 Holders. This suction base does NOT have, or include, a RAM 1" rubber connection ball. Two self tapping screws are supplied with the suction cup base.
Material:
High Strength Composite
TIP:
When attaching the suction base, it must be clean and dry and so must be the surface it affixes to.
An alternative method is to attach an adhesive rose pad the RAP-350 on to the dash area and fix the suction base onto it.
