RAM Rectangular base - B Series - Curved extension plate with AMPS hole pattern

RAM-B-125BU – RAM® Curved Extension Base with 1" B-Size Ball

The RAM-B-125BU is a curved offset base with a 1" B-size rubber ball, giving you an adjustable, angled mounting point for medium-weight devices such as GPS units and radar detectors. Originally designed to sit a GPS ahead of an aircraft yoke, the offset works just as well on a dash or panel where you need the device pushed forward and up.
