Product Description
Rail Clip (also known as Tension Clamp) is a critical component in rail fastening systems, used to securely fasten the rail to the sleeper or rail base, manufactured from spring steel bar or plate. Its primary function is to hold the rail firmly in place while allowing limited expansion and contraction of the rail due to temperature changes, preventing track deformation or damage.
