The rear corner profiles extend 3 cm beyond the height of the unit and contain a buttonhole for an easy attachment to the wall.
The main advantages are :
A simple, tried-and-tested mounting system that makes it easy to hang the unit from two anchor points (and which allows small level adjustments).
NB: The corner profiles are attached to the structure using the screws supplied. Wall plugs and screws are not provided, as they depend on the nature of your wall.
