The gauge block is a part of the connecting piece in the track fastener, which is to assume the role of adjusting the gauge and insulating the current connection between the rail and the ground. The gauge block is mainly produced by injection molding machine, and the material is mainly composed of nylon PA+ glass fiber GF, also known as modified nylon. High mechanical strength, heat resistance, wear resistance, high rigidity, dimensional stability. It is divided into WJ-8 gauge block, switch gauge block, switch nylon gauge block.

Reliable Gauge Accuracy
Precision-molded to achieve a true interference fit with the rail foot (UIC 60, 136RE, etc.) and tie shoulder. Effectively maintains precise rail gauge under heavy axle loads and continuous vibration, ensuring long-term track stability.
