These optional Wine Rack clips enable you to connect two or more individual Wine Rack Systems together. These clips, not only provide an extra row of storage, but they also provide strength and stability to your Wine Rack. When connected these clips add an additional 6.5cm in height to your combined Wine Rack. These clips can also be used as spacing templates whilst installing custom made Wine Racks. These clips are used to connect Wine Rack systems together horizontally as well as vertically. If connecting two or more systems together vertically, we also recommend purchasing a set of Wall Brackets. These brackets secure your Wine Rack to the wall and prevent the whole system from becoming unstable.
