The FERBOX® reinforcement attachments are prefabricated reverse bend attachments for simple non-positive connection of reinforced concrete components of different construction phases. This allows walls, ceilings, corbels and staircases to be joined together retrospectively and reliably. For over 30 years, H-BAU Technik has been producing and selling single- and double-row reverse bend connectors of various standard and custom designs with a wide variety of flashing boxes.
