The RAM-B-101-A-NKU consists of a SHORT double socket arm and two 2.5" diameter round bases that contain the universal AMPS hole pattern. The mount is designed with a 1" diameter patented rubber ball and socket system that has adjustment points at both ends of the double socket arm; allowing for almost infinite adjustment and perfect viewing angles. The hole pattern found on the round base adapter will connect to many RAM cradles. The included RAM’s patented design dampens shock and vibration, helping to extend the life of your device. The double socket arm tightens with a provided socket head cap screw and acorn nut. The mount can be disassembled, adjusted and tightened with the use of an allen wrench (cannot tighten by hand).
