K2 Systems SolidRail Light Solar Mounting Rail 4.80 m (2004395)

Weighing in at just 0.75 kg per metre, the K2 Systems SolidRail Light proves that high load capacity doesn't have to come with heavy dead weight. This 4.80 m aluminium rail is the backbone of reliable roof-mounted photovoltaic arrays, offering exceptional structural integrity while keeping roof load to a minimum — a critical factor for both residential and commercial installations.

The SolidRail Light is a versatile mounting rail engineered for pitched roofs. Its three-channel design — two upper channels for module clamps and one lower for roof connections — works seamlessly with the full range of K2 mounting components, including Climber, CrossHook, and OneMid/OneEnd clamps. Manufactured from aluminium EN AW-6063 T66 with a natural mill finish, it delivers excellent corrosion resistance and long-term durability.
