These ascending structures have been designed to slot into the vertical rebates in a wall and be capable of installation at differing heights. The structures act as levers to create friction forces between the structure and the internal sides of the wall rebates. Constructed from laminated laser cut MDF they are hollowed out internally and have concealed steel weights to create the required friction forces.
