To hang a chandelier on the ceiling you have to set up a hook.

This can be achieved by inserting into the floor a metal hook between a pignatta (the bricks that make up the slab) and the other.

Or you can use a special "anchor" dowel that snaps into the brick and expands into empty spaces like anchor.

At this hook we will fix the chandelier, connect the ignition cables and close the cover bell.
