Time-saving, reliable production
The connector screws allow for simpler, more efficient, and more reliable work on corners without a riveting pin or chisel hammer. Thanks to new mounting sets for the outward-opening barrel door hinges, the adjustment range has also been optimised significantly. The existing drilling pattern on older mounting sets can still be used. In addition, the multifunctional die used to produce the profile has also been developed. This allows all significant processing steps to be completed with a single tool, such as punches for nail and/or injection holes, base and casement drainage or docking frame/casement stops. Another new feature is the two-piece door and replacement threshold, which combines the advantages of a continuous door threshold with a threshold installed between the frame. The tilting system technology ensures simple, economical installation. Using the new replacement threshold improves installation in renovations of older buildings. Thanks to its outstanding diversity and many new functions, the heroal D 72 fulfils all current requirements and embodies a well-designed system solution for every installation situation and architectural style, from private homes to buildings, new construction, or renovations.
