System DFF 21
The fastening system DFF 21, a single support point with screw-dowel combination for anchoring on slab tracks, is based on the well-proven fastening solution W-Tram. A reinforced base plate offers a bigger surface for traffic load distribution: the system is able to withstand axle loads of up to 26 t and is therefore suitable especially for Metro and conventional rail projects.
