The 65mm Square Rainwater Downpipe (4m, Black) is a primary vertical drainage component designed to transport collected surface water safely from roof guttering down to ground-level drainage systems. Manufactured from high-grade, lightweight uPVC, this 4-meter length provides substantial vertical coverage for standard residential or low-rise commercial properties, balancing ease of handling on-site with efficient span coverage.
 
Engineered with a robust square profile, the downpipe offers high hydraulic capacity while maintaining a sleek, modern exterior aesthetic that complements contemporary building designs. It integrates smoothly with standard 65mm square fittings, socket connectors, and wall clips, creating a secure, rigid vertical column capable of handling high-volume stormwater runoff efficiently during heavy downpours without deflection or leaking.
 
Manufactured to high industry standards, the durable black uPVC material is UV-stabilized to resist fading, discoloration, and structural degradation caused by prolonged exposure to sunlight and harsh weather conditions. It provides a long-lasting, low-maintenance drainage solution that ensures reliable exterior performance and a clean, uniform finish for residential and commercial properties.
