Copper Guttering Hollow Pipe Ring Chain (Pack of 8 for a 2.5m Drop) Description Copper rain chains and cups can be used to add a distinctive and interesting visual aspect to your guttering creating interesting garden features when used in conjunction with planters, ponds, green houses, gazebos and water butts. The copper rain cups are supplied in metre lengths and can be easily separated and joined together to create the required drop. Each of the chain designs are supplied in packs of metre lengths to create a 2.5m drop as several lengths of chain must be used per outlet to make them effective. We strongly recommend that they are only used as a decorative feature and not as the main form of downpipe for your metal guttering or plastic guttering. For installation to your copper or other metal guttering we would recommend a simple stainless steel bar laid inside the metal gutter with the cups hanging off it, however the cups would also require anchoring at the bottom.
