Rail skl Clip Fastening System
The Railway SKL Clip is a torsion-resistant elastic fastener engineered for demanding railway track applications. Formed from high-grade silicon-manganese spring steel, it delivers consistent clamping force through its unique helical leg design. This clip secures rails firmly to concrete sleepers while accommodating vertical and lateral track movements. Its proven performance makes it the preferred choice for high-speed passenger and heavy-haul freight lines globally.
