Rail Plastic Dowel

Rail plastic dowel, also called rail plastic sleeve, is a counter-party of screw spike. It must be pre-imbedded into the concrete or wooden sleeper and installed together with screw spikes to fasten the rail tracks. The main materials of AGICO rail plastic dowel are PA66 and HDPE.

AGICO RAIL is a professional railway fasteners manufacturer and we have been supplier for 50 years. With granted ISO9001-2008 certificate, AGICO RAIL can produce many kinds of international standard types of rail fasteners such as AREMA, BS, GB, UIC or DIN.

Rail Plastic Dowel In the Rail Fastening System

In the rail fastening system, the plastic dowel should be pre-inserted into the concrete sleeper separately before assembling the rail fastening system parts. It is used to guarantee the good connection and linkage of the rail fastening system with the concrete sleeper. When we use the rail fastening system, the plastic dowel can performed as the fastening base.
