What are the advantages of using the SKL21 rail clip?
The advantages of the SKL21 rail clip include its high clamping force (≥20) kN), which provides superior stability and resistance to rail movement, and its elasticity, which allows for long-term, consistent pressure and reduces stress on components. It is suitable for both high-speed and conventional rail lines on ballasted tracks, meets EN 13481-2 standards, and offers features like gauge adjustment, high creep resistance, and electrical insulation.

Performance and stability
- High clamping force: The SKL21 offers a higher clamping force (≥20) kN) compared to some other designs, ensuring a secure and stable connection between the rail and sleeper.
- Superior stability: It provides a high resistance to longitudinal forces, which prevents rails from shifting during acceleration and deceleration, enhancing safety by avoiding dangerous gaps.
- Resistance to rail rotation: The design prevents rail rotation, which is crucial for maintaining the track's integrity, especially at turnouts where complex forces are applied.
- Fatigue resistance: The clip is designed for long-term durability, with a fatigue life of 5 million cycles at a 9.1mm spring deflection without breaking.
