The case hinge kit allows it to join two cases at a free angle. It contains:

two joint elements
four screws
a connection cable between the cases.

This type is designed for an application where the lower case is already fixed above the surface (e.g. when mounting a third case to a combination of two cases connected with the hinge kit type 1).

Via the connection cable the bus and power supply is shared between both cases, so no extra power supply / second MASTER module is needed for the additional case.
