FSB 1005
The Wedge

Modernized by Johannes Potente in the 1960s, FSB 1005 reinterprets Max Burchartz’s 1931 design for a universal handle. With its crisp wedge shape, it became a favorite of Egon Eiermann and remains a go-to solution in the renovation of postwar modernist buildings. Notable applications include the “Langer Eugen” tower and the former Chancellor’s Bungalow in Bonn. A classic with enduring architectural appeal.
