ABSTRACT:
A frame structure (1) having an open top and an open bottom is for mounting on a pallet (6) to form a plastics retaining wall. The side walls (2 and 3) of the frame have upwardly extending flanges (16, 16a and 17) at the top edge and downwardly extending flanges (7, 7a and 8) at the bottom edge. Two similar frame (1) are stackable, one on the other to extend the height of the wall with the downwardly extending flanges of the upper structure received between the upwardly extending flanges of the lower structure so that the flanges bridge both frames to restrain relative horizontal displacement therebetween. The flanges (7 and 16) have apically profiled edge parts (30) which snap engage between respective structures in forming the stack to restrain the upper frame from lifting relative to the lower frame. The frame strucutre may be collapsible to form a flat pack.
