An arrangement is disclosed for the preferably automatic coating of objects with a coating material, in particular coating powder. The arrangement includes at least one spray device having a spray nozzle via which the coating material is dispensable in a main spraying direction. An extension is further provided, wherein an end region of the extension facing the spray device is preferably detachably connected to an end region of the spray device associated with the extension opposite from the spray nozzle. The arrangement further includes a preferably horizontally extending guide via which the extension with the spray device connected thereto can be longitudinally moved in the direction of extension of the guide relative to the object to be coated. The main spraying direction of the spray nozzle may be implemented so as to deviate from the direction of extension of the guide by a predefined or definable angle.
