Gamber-Johnson docking cradles for the Dell E6400/E6400ATG and the Dell E6500 computers feature brackets that restrain either the Dell E-Port or E-Port Plus office port replicator. The port replicator attaches to the cradle using brackets located at the rear of the cradle. The built-in positioning guides ensure that the port replicator is firmly seated and properly positioned to the cradle every time.
