The RAM Twist Lock Suction Mount simply attaches via the suction cup base to a windshield of your vehicle or any other perfectly flat surface for an easy and safe way to mount a camera. The Rubber ball and socket technology allows for almost infinite adjustment and perfect viewing angles. High quality materials ensure your unit is safe, secure, and within easy reach. RAM's patented design also dampens shock and vibration helping to extend the life of your mobile device. Components: RAM-B-201, RAM-B-202A, RAM-B-238 and RAP-224-1. 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.
