SKL21 Railroad Clip
The SKL21 Rail Clip, which belongs to the Vossloh SKL tension clamp range, is known for its W-shaped structure and is commonly referred to as a W rail clip. Rail clip is also called elastic rail clips, track clips, railway clips, or railroad sleeper clips, rail clips apply clamping force through bending and twisting. This secures the rails, preventing lateral or longitudinal movement, maintaining the track gauge, and ensuring safe rail vehicle operations. GNEE Rail manufactures and exports a diverse range of rail clips, including W-shaped, E-type, SKL, PR series, NABLA spring clips, Fast clips, and Fist clips, ideal for metro, high-speed, and intercity transport systems. Our products are used in Europe, the U.S., Canada, and around the world. We also offer customized railway accessory solutions and are committed to providing fast, reliable service.
