Rail sKL Clip Fastening System

The SKL Clip is a German-origin fastening system component known for its wedge-shaped design that provides consistent clamping force through spring action. It is particularly suited for ballasted and ballastless tracks in high-speed and heavy-haul applications, offering excellent resistance to rail creep and longitudinal movement.
