Components adapted to be used in a parking barrier. A pair of prefabricated units are provided to be used at the parking lot when a parking barrier is set up. One of the prefabricated units includes a mounting bracket which is adapted to be fixed to a standard and a shaft which is fixed to and extends from the bracket. The other of the pair of prefabricated units includes an arm carrier which is adapted to be connected with an elongated barrier arm and a bearing for mounting the arm carrier swingably on the shaft. Thus, these prefabricated units can be assembled at a parking lot with a standard fixed to and extending upwardly from the ground and with an elongated barrier arm to complete the parking barrier.
