The structure includes pins directed through each corner of the free ends of the base plates, and may further be provided with tether lines, with a plurality of the tether lines utilizing adjusting means for fixedly anchoring the ladder to the plate structure. Further refinement of the organization includes the flanges in hingedly intercommunicating relationship relative to one another to permit interfolding of the structure for ease of transport and storage.
