The RAP-365B-1-339U is a triple magnetic base adapter, each connected by a 1" ball and socket joint. The three bases are connected by a high strength composite adapter plate which contains the 4-Hole AMPS hole pattern in the center, allowing you to adapt any RAM Mount to the magnetic bases. Each magnetic base contains three rare-earth magnets (nine total) which lock up securely against any steel or ferromagnetic surface. The soft composite coating on the magnetic adapters prevent scratching or scuffing of the surface you are attaching to.
