The retaining flange is not a required item regarding the listing of the sprinklers. It provides an option to the contractor as a method of securing the piping to prevent axial or lateral movement of the sprinkler either away from the ceiling or the wall by an occupant. If it is not used because of installation constraints, some other approved method of securing the pipe must be provided to prevent an occupant from inflicting self-injury.
