K2 Systems MultiRail 25 CSM Aluminium Zonnepaneel Montagerail 2,55 m Zilver

The MultiRail 25 CSM stands apart from conventional mounting rails by combining a low 25 mm profile with a robust click-in channel, enabling fast module installation without compromising structural integrity. Its 40 mm width and precision-engineered geometry allow direct integration with K2 clamps and roof attachments, reducing the need for additional adapters on pitched roofs. This rail is ideal for installers who demand both speed and long-term reliability in residential and commercial PV projects.

Highlights

• Extruded from high-grade aluminium EN AW-6063 T66 for exceptional strength-to-weight ratio
• Click-in channel accepts K2 OneMid and OneEnd clamps for tool-light module fixing
• Anodized silver finish provides superior corrosion resistance in outdoor environments
• 2.55 m length minimizes joints on standard module rows, saving installation time
• Compatible with K2 MiniRail and SpeedRail systems for flexible roof layouts

In daily use

On the roof, the MultiRail 25 CSM proves its worth through straightforward handling. At approximately 1.1 kg per metre, a single rail is easy to position and secure to K2 roof attachments. The click-in channel lets installers slide clamps into place and tighten them with minimal effort, while the anodized surface resists scratches and weathering. Static calculations and TÜV Rheinland certification back its performance under high snow and wind loads, giving planners confidence in long-term durability.
