Elastic rail clip is one of the common railway fasteners in the railway system. In general, elastic rail clip is made of forged spring steel and has many applications. No matter as a part of rail fastening system or as a rail fastener, elastic rail clip is used with other railway track parts, such as railroad spike, rail pad, tie plate and plastic dowel.
SKL rail clip, also called skl tension clamp. German railway is the first to develop SKL elastic rail clips. And then, they are proved to be reliable on the concrete and wooden railroad ties. SKL rail clip include many sizes, such as skl1, skl3, skl12, skl14, and etc.
