This 8.5 in. black lotus aluminum rain chain is composed of precision-cast wide-mouthed lotus cups that are layered together. The slightly concave petal design at the cup mouth efficiently accumulates and guides water flow. It is not only a silent poetic water curtain but also a tool-free eco-friendly downspout system. Aviation-grade aluminum materials are treated with a matte black coating, which is rust-resistant and weather-resistant, remaining as good as new all year round. Each cup measures 4.5 x 2.25 in. with a bottom hole of 0.75 in. . The length can be customized by freely adding or removing chain links. When paired with a triangular hook, it can instantly replace the traditional downspout. Paired with a water basin or anchor base, it not only adorns the porch, courtyard and hedges, but also collects rainwater in a sustainable way, adding an elegant and modern black landscape to the building. Size: large. Material: Metal.
