The racks are made from extruded aluminium and coated with a natural satin anodising. The individual modules slide and snap together. Each module forms the lower half of one bottle cavity and the top of the next. In this way stacks can be built to the required height working from the base up. Multiple stacks can then nest side by side to create a continuous storage wall. Here are the basic components:

Each module is supplied with a centre hole through which a tube is inserted once stack is assembled. Wall brackets hook around this tube and screw to the wall to secure. Stacks must be positioned on a horizontal surface with adequate strength to support the combined weight of rack and bottles.
