You can connect from the roof drain to the downspout and fittings using the system.
This is a series of downspouts and connecting fittings designed to guide rainwater to the ground. To allow for selection based on drainage capacity, five sizes of downspouts are available: outer diameters of φ165.2, φ139.8, φ114.3, φ89.1, and φ60.5. Since these sizes conform to JIS standards, versatility is improved, making it easy to connect with roof drains and drainage pipes. Made from stainless steel (SUS304) that is resistant to rust and has excellent strength, the material undergoes forming and arc welding to ensure durability. Additionally, a clear (plain) ceramic-based coating is applied to the surface finished with a hairline texture to significantly enhance weather resistance. 【Product Lineup】 ■ Downspouts ■ Decorative catch basins ■ Fittings ■ Grip hardware *For more details, please refer to the PDF document or feel free to contact us.
