Rail Insulator
We proudly produce E type rail insulators and guide plates for both SKL rail fastening and Nabla fastening systems. Crafted from robust PA66 material, our rail insulators come in a variety of colors, including white, dark brown, and black. These high-performance nylon insulators are designed to precisely adjust rail gauge and effectively insulate the rail from both ties and clips, ensuring optimal functionality.
The exceptional material properties of PA66 are outlined below.
