The RAM B202 Round Base is a marine-grade aluminum alloy plate 2-1/2 inches in diameter with a one-inch RAM ball. Recommended for use with the RAM Aqua Boxes and Radar Plate, this item is perhaps the most versatile base of all. Four of its seven holes conform to the the industry-standard AMPS (American Mobile Phone Standard) mounting pattern, which matches many factory-supplied device holders, including the OEM holders for the Magellan RoadMate and Magellan Maestro 3000 and 4000 Series. The remaining three holes are spaced equilaterally, should you prefer a configuration like that for some reason.
Like all bases, if you are willing to drill some holes, the B202 Round Base could also be used as a sturdy mount. Other RAM bases with an AMPS compatible hole pattern include the MA4 Universal Base for Factory Holders and the B238U Diamond Base.
