Railway sleeper dowels are pressed into concrete sleepers and assembled with sleeper screws, guide plates and rail clips to secure the rails. Rail plastic dowels are commonly used in SKL fastener systems. Our sleeper dowels are made of PA66 or HDPE.
The railway dowels produced by Kingrail Parts can meet DIN, UIC, AREMA/ASTM, JIS and other standards. We can customize sleeper dowels according to customers' specifications and requirements.
