SKL21 Railway Track Clip
The SKL21 Rail Clip is a Vossloh SKL tension clamp featuring a W-shaped design, which is why it is often called a W rail clip. Rail clip is known as elastic rail clips, track clips, railway clips, or railroad sleeper clips, rail clips work by creating clamping pressure through bending and twisting. This ensures the rails are securely fastened, preventing any shift that could disrupt the track gauge and ensuring the safety of trains. GNEE Rail manufactures a broad range of high-quality rail clips, including W-shaped, E-type, SKL, PR series, NABLA spring clips, Fast clips, and Fist clips, suitable for metro, high-speed, and intercity transport systems. These clips are used extensively across Europe, the U.S., Canada, and other regions. We also provide customized solutions for railway accessories with fast and responsive customer service.
