CENTRAL DOOR KNOB
Between 1959 and 1962 Luigi Caccia Dominioni designed three historic models with the same design matrix and the same characteristic handle, but with different functions, determined by the position of the pillar: a knob, with a central pillar, and two handles , one with a straight pillar, placed in an offset position, the other with an angled pillar inclined out of axis to facilitate the lever.
