K2 BasicRail System
All-rounder with only 4 installation steps. Floating with controlled thermal linear expansion.
The BasicRail mounting system (former SpeedRail) for photovoltaic systems has been specially developed for trapezoidal sheet metal roofs. In Germany, the system has an abZ certification.
- The proven long rail system for trapezoidal sheet metal applications as well as floating with controlled thermal linear expansion.
- Our best-selling system - over 2 GW installed worldwide
- All-rounder with only 4 installation steps - also suitable for high load

K2 BasicRail System
System variant
BasicRail systems can now be planned with an elevation. This improves the rear ventilation of the modules and helps with the installation of micro-inverters and power optimisation.
We recommend using this component in very warm regions or to optimise module performance.
RailUp is supplied as a set and does not require any additional material for installation.

BasicRail on FischerTHERM sandwich panels with abZ
The direct connection of BasicRail with BasicClips and thread-forming screws on FischerTHERM sandwich panels has a general building authority approval (abZ) from the DIbT. This type of installation with a building authority approval (Z-10.4-901) is unique in Germany. A low time requirement results from the high installation speed of the BasicRail system and the direct fastening of the system in the sandwich panels.
