The fastener unit has an assembly board (11) for assembling a door actuator i.e. mechanically actuatable door actuator, at a retainer. The assembly board comprises one or multiple projections (17) that are formed with respective holes (20). The assembly board comprises a stop element (50), which is formed for fastening a counter stop element i.e. monotonous projection, of the door actuator to stop an assembly movement of the door actuator at a defined position. The hole of each projection is aligned with a hole of a housing of the door actuator. The retainer is a door leaf, a door camber, a wall or a ceiling. |
