Rail skl Clip Fastening System
The Railway SKL Clip is a precision-engineered elastic fastener designed for demanding rail fastening applications. Forged from high-grade spring steel, its unique S-shaped geometry with twin legs delivers exceptional clamping force and deflection capacity. This clip utilizes rotational installation to achieve pre-determined tension. It serves as the standard fastening solution for high-speed railways and heavy-haul corridors worldwide.
