• RAM Suction Cup Base - Dual Cup - with AMPS hole pattern
The RAM-B-189BU consists of a double 3.76mm twist lock suction cup base. Included is a hole pattern that will allow attachment to all RAM bases that contain the universal AMPs hole pattern.

The typical base used is the RAM-B-202U round base with 1" ball but a RAM-202U with 1.5" ball is a better alternative for high vibration environments.


This forms the basis of a rock solid aviation EFB mount.
