ABSTRACT:
An arrangement for mounting a door closer to a stationary or movable door frame. The door frame is provided with a channel rail having longitudinally extending undercut grooves which form transverse guide tongues. Guide projections provided on the door closer are adapted to be received in the undercut grooves so as to be disposed behind the guide tongues. At least one thumbscrew is supported at the door closer and arranged so as to press the guide projections against the guide tongues to thereby mount the door closer at the channel rail.
