Wittgenstein’s ingenious idea: to enable fittings to be attached to narrow stiles whilst avoiding hands getting caught between slamming face and door jamb, in the 1920s the philosopher Ludwig Wittgenstein had a cranked door handle made for the slamming face to his own drawings that he combined with an uncranked male lever handle on the leading face. This idea had a crucial impact upon the design of handle ranges and continues to do so today. FSB includes just such a set of narrow stile door lever handles in each of its new handle collections.
