SKL Rail Clip vs E Type Elastic Clip
SKL clips (like SKL1, 3, 12) and E-type clips (E1609, E2009) are both widely used elastic rail fasteners, but they differ in design, load capacity, and application; E-clips are robust, stubby, paperclip-like, suited for heavy haul with high toe loads, while SKL clips are tension clips known for global usage and versatility, providing durable rail alignment, with both generally made from high-strength spring steel to secure rails to sleepers.
SKL Rail Clip (Tension Clip)
- Design: A tension clip, often seen globally, with types like SKL1, SKL3, SKL12, etc..
- Function: Provides positive rail fastening, ensuring alignment and protecting rails from high pressure.
- Material: High-strength spring steel.
- Usage: Extremely common worldwide for various track applications.
