RainTube® is the first system to work with any roof/gutter combination and accommodates exposure to varying levels of debris. It is made from 100% recycled HDPE, which is virtually indestructible and comes with a transferable lifetime warranty. It is Cradel-toCradle certified as sustainable. RainTube® prevents downspouts from clogging while collecting rainwater at high volumes—even through heavy debris.
