Surely 'door furniture' describes a whole range of objects that one could buy, for example, at a DIY store? In the 'door furniture' section, one would expect to find: knobs, knockers, key holes, handles, thumb latches, escutcheons, security chains and fingers plates. I hate jargon in the wrong place, or the random formation of unnecessary 'new' words. But in this case, the use of the generic term 'door furniture' seems entirely appropriate. What else could this section in a DIY store be called? 'Door stuff'?
