We proudly manufacture the E type rail insulator and guide plate tailored for both SKL rail fastening and Nabla fastening systems. Our choice of material for these rail insulators is top-grade PA66, available in a sophisticated palette of white, deep brown, and classic black. These high-performance rail nylon insulators play a crucial role in adjusting rail gauge and ensuring seamless insulation between the rail and ties, as well as clips.
Below are the exceptional material properties of PA66, highlighting its reliability and strength.
