Railroad Steel Rails SKL Clips

Railway Clip is used to fasten the rails to the underlying base plate together with the concrete sleeper. A variety of different types of heavy-duty clips are used to fasten the rails to the underlying baseplate or Sleeper, one common being the E Clip, which is shaped like a stubby paperclip. Another one is the SKL Tension Clamp, which is also the most widely used type all over the world. Others like KPO Clamp and Nabla Clip, also used in different situations.
