K2 MultiRail 25 250mm Rail: The Fast, Flexible Solar Mounting Solution for Metal Roofs

The K2 MultiRail 25 250mm Rail (K2-2002793) is a time-saving, direct-fix solar mounting solution designed for trapezoidal metal roofs. With its extended 250mm length and factory-applied EPDM backing, this rail provides fast, secure installation with integrated waterproofing. The longer rail length is ideal for installers seeking fewer fixing points and greater layout flexibility across wider panel spans.

Extended Rail Length for Fast, Efficient Installation

The MultiRail 25 is built to simplify metal roof solar installations by offering a longer rail profile that covers a wider surface area. This reduces the number of fixing points needed per panel, speeding up the fitting process and saving on installation time and materials.

Its direct-fix system uses self-tapping screws that secure the rail straight to the trapezoidal sheet without the need for additional brackets or pre-drilling in most cases. This quick-fit approach helps installers move efficiently through large-scale commercial projects.

Integrated EPDM Backing for Instant Waterproofing

Like the MultiRail 10, the MultiRail 25 features a factory-applied EPDM backing that provides immediate sealing at each fixing point. This integrated waterproofing eliminates the need for separate sealing washers or adhesives, offering reliable weather protection straight out of the box.

The EPDM layer is specifically designed to maintain a durable, long-lasting seal on metal roofs, helping to prevent water ingress and reducing future maintenance risks. It’s a smart, time-saving feature that improves installation quality and speed.

Compact, Space-Efficient System for Metal Roofs

Despite its longer rail length, the MultiRail 25 maintains a compact, low-profile structure that blends neatly into the roof surface. This helps minimise wind uplift and ensures the system remains discreet, making it perfect for commercial buildings, warehouses, and agricultural units.

The system’s small footprint also makes it easy to transport, handle, and position on-site, offering installers a practical, lightweight solution for busy commercial jobs.
