SKL21 Rail Clips
The SKL21 Rail Clip, a variant of the Vossloh SKL tension clamp, has a distinctive W-shape and is commonly called a W rail clip.
The elastic rail clip, or railway clip, track clip, and railroad sleeper clip, applies clamping force through bending and twisting, creating a secure connection between the rails. It prevents longitudinal and lateral movement of the rails, keeping the track gauge stable and ensuring the safety of rail vehicles. We GNEE rail are dedicated to manufacture and export top-tier rail clips, including W-shaped, E-type, SKL, PR series, NABLA spring clips, Fast clips, and Fist clips. These products are used in metro, high-speed rail, and intercity transportation systems around the world, including in Europe, the U.S., and Canada. We also offer integrated solutions for customized railway accessories. Contact us for more details.
