<p>The multistage platform assembly has two fasteners for vertical struts. The platforms are designed for optical interconnection in making a variety of assemblies, e.g. for forming stairs, flower display stand, or vehicle loading platforms. The platform comprises freely overhanding cantilevers. The platform has square hollow sockets near the corners. Rotation is prevented by square struts which pass through these sockets. The struts can be telescopic for length adjustment.</p> |
