Rain Chain Tapered Gutter Outlet Adapter
A drop-in tapered spout that replaces a downspout with a rain chain. The 40 mm cone tapers from 74 to 46 mm OD, so it self-centres in any round gutter outlet hole from about 48 to 72 mm. The 100 mm flange sits on the gutter floor with three 4.5 mm holes for #8 screws or 1/8 in rivets and a bead of gutter sealant. A 12 mm crossbar spans the bore: the chain's top link hooks over it, or an M5 eye bolt goes through the 5.5 mm centre hole.
