Each of the rails (7) on the supporting walls (6) terminates forward at its pull-out end in a raised endstop (9) as opposed to a second endstop (19) which co-operates with endstop (9) in the pull-out setting and which is fitted at a distance from the rear edge (18) on bearing rims (16) engaging the opposed and parallel grooves (8) arranged between the respective rails (7). Guides (11) fitted to the underside of the rails (7) are set back inwards relative the endstops (9, 10) to take the top sides of the bearer rims (16). Each rail (7) is fitted at its rear pull-out end with another raised endstop (10) to work with the second endstop (19). Endstop (20) reaching downward spaced from the front edge (17) of the rims (16) works when pushed fully in with the raised endstop (9) at the front pull-out end of the rails (7). The spacing between the rails is such that the rims and fitted endstops (19, 20) slide with tight clearance between the rails.
