The front plate (14) has at least one of its upper and lower edges provided with an inwardly directed flange (15,16). The flanges support the gable plate through location against support components (17). A beam (21) is adjustable, by a catch (23) accessible on the front side of the gable plate, between a lock position in which the beam engages with a tub component (17) and a free position in which it is disengaged from that component. |
