The SKL 12 elastic rail clip is a classic model from the German Vossloh fastening system, widely used for securing rails on concrete sleepers. Made of high-tensile spring steel and coated with protective color painting, it offers excellent corrosion resistance and long fatigue life, suitable for various railway track gauges.

The SKL 12 clip provides a clamping force of approximately 9–12kN with an elastic deflection of 8–12mm, ensuring excellent rail stability. The color coating not only enhances protection but also facilitates quick identification of clip types on site.
In addition to color painting, GNEE RAIL offers other surface treatments such as black oxide, Dacromet, and hot dip galvanizing (HDG) to meet different environmental protection needs.
In addition to SKL 12, GNEE RAIL also supplies SKL 1, SKL 3, and SKL 14 clips, as well as E-type clips, rail pads, insulators, screw spikes, and fish plates. The company offers custom design, sample testing, and installation technical support for complete railway fastening solutions.
