Overview

The RAM-B-138-C consists of a 6.35cm (2.5") diameter round base that contains the universal AMPs hole pattern,
LONG double socket arm and diamond base adapter. The mount is designed with a 2.54cm (1") diameter patented
rubber ball and socket system that has adjustment points at both ends of the double socket arm; this

diamond base adapter will connect to most RAM cradles. The included RAM’s patented design dampens
