FERBOX® reverse bending connectors are used for the simple and safe connection of reinforced concrete components of different construction or concreting sections. Whether walls, ceilings, brackets, or stairs, this solution allows you to connect a wide variety of components in a friction-locked manner. The new FERBOX® generation combines the properties of transverse or longitudinal splines in a single design with the nubbed box.
As the first  reverse bending connector on the market, the new FERBOX® generation has received an ETA and thus offers more planning security.
Shortly we will provide you with the technical information and software for download here.
