SKL 14 fastening system:

?

Features:
# Skl 14 R tension clamp with 1.8 mm fatigue strength
# Rail tilting protection by middle bend of the tension clamp and special design of the angled guide plate
# Pre-assembly of all components in the sleeper factory possible
# Reduction of maintenance costs by permanent elastic tensioning of the rail with tension clamps (2 x 12 kN toe load)
# Gauge adjustment ±10 mm in 2.5 mm steps
