The fischer connector PFUF 41 is a connecting element for creating multi-dimensional rail constructions with the fischer push-through connector PFCN. The various shapes of the connectors offer flexibility when it comes to the installation of rail constructions. The PFUF cap profile is a space-saving solution for the construction of rail crossings. The galvanised zinc design is suitable for installations in buildings, the hot-dip galvanised or zinc flake surface coating and stainless steel designs are suitable for installations outside and in highly corrosive environments.
