Use this 3 part SimpleSpecs™ master specification to specify the repair and replacement of hardware for doors, windows, screens, awnings, and shutters, and weatherstripping and thresholds.
This section includes the most commonly encountered types of metals; brass and bronze for operable hardware; copper and zinc for weatherstripping; and brass, bronze, and cast iron for thresholds. Other metal types can be added by the specifier.
Due to the wide range of historic and replacement hardware, this section provides a framework for specifying new and replacement hardware. A detailed hardware schedule must be developed to suit the individual project’s needs.
This section must take into account the effects of current accessibility codes, laws, rules, and regulations, including the Americans with Disabilities Act, and their effect on door hardware. While some projects may be excluded from compliance, others will need to comply and historic hardware requirements must be modified accordingly.
While reference materials exist on the subject of windows and their hardware, there is not currently available a comprehensive resource for the restoration of historic door hardware. Specifiers should contact manufacturers of period hardware for assistance.
