FactoryRegistry lists 18,367 facilities whose primary industry classification is one of the 6 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced doorlocks and locksets; screen, storm door, and window hardware; cabinet and closet hardware; hinges, padlocks, door controls, and other builders' hardware (including architectural trim hardware), in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.
