The NABLA rail clip is specifically designed to support the NABLA fastening system, which is a popular choice for tram tracks throughout Europe. It is suitable for use on both ballasted and concrete sleeper tracks, delivering excellent performance on tight-radius curves. The clip ensures superior electrical insulation, effective lateral force absorption, and exceptional durability, thanks to its glass fiber-reinforced gauge blocks. GNEE Rail manufactures a comprehensive range of rail fasteners, including rail clips, joints, screws, anchor bolts, clamp plates, fishplates, and fishplate bolts, meeting global standards such as GB/TB, AREA, UIC, BS, DIN, ASTM, and AS.
