This high-quality rainwater outlet consists of an HDPE pipe and a round 1 mm thick EPDM flange. Using a patented expansion system, the flange is securely fixed to the HDPE pipe. As the flange is pre-attached, fast and efficient installation is guaranteed — all that is required is fixing the outlet to the roof. This product is therefore suitable for both new build and renovation projects. As the dimensions precisely match existing couplings, it can be perfectly connected to the existing drainage channel.
