Honeywell FlexDock Base Desktop 852-920-002 is the desktop base used to assemble a FlexDock setup for a mobile computer. Honeywell lists it in a build-your-own USB configuration, giving the base a role as the platform for a modular docking arrangement.
The mobile-computer cup is a separate part and supports CK3 and CK65 devices. The documented setup also lists AC adapter 851-812-001 and an AC power cord as separate components. This lets the base be combined with the relevant cup and power components for the documented configuration.
