There are spacers (4) to be fastened on the building wall, onto which the mounting frame (1) is insertable at different distances. The frame can be fixed at the respective distances by securing members (9) on the spacers. Each spacer is fitted with a threaded section (6) for securing to the building wall. The base-shaped securing members are connectable to the mounting frame. Pref. the spacers have parallel slots (5a) or grooves for retention of the securing members at different spacing from the threaded section.
