While the spring arm ends lie on the rail foot and exert the clamping force, the middle loop of the clamp has a certain distance to the railfoot and only activates at excessive rail tilting.
The typical field of application for SKL21 clips are High Speed systems on ballasted track.
Material:
The rail clip SKL21 is manufactured from hot rolled spring steel, grade 38Si7 (DIN 1.5023).
