A cantilever system includes at least one profile rail and at least one bracket for installation in the profile rail. The profile rail includes an elongated opening for the bracket and opposing counter-surfaces inside the profile rail for pulling and pushing caused by the bracket when installed on the profile rail. The bracket includes a widening to be fitted inside the profile rail arranged to form a pulling surface for creating the pulling when the bracket is installed in the opening in the profile rail, and a pushing surface for creating the pushing when the bracket is installed in the opening in the profile rail. The cross-section of the bracket is arranged, in the part that is outside the profile rail, to be at least locally a sideways opening U-profile, when the bracket is installed in the profile rail. The bracket is manufactured from a single plate piece by bending.
