Rail e Clip Fastening System

Railway E Clips are elastic rail fasteners manufactured from high-grade spring steel, characterized by their distinctive E-shaped configuration with three functional legs. These components secure rails to sleepers through elastic deformation, converting installation deflection into sustained clamping force. The symmetrical design ensures balanced load distribution while accommodating track curvature variations and thermal expansion cycles.
