Cirecast was retained to provide architectural hardware for the restoration of the Kansas State Capitol. This project required that new, historically inspired hardware work with existing mechanical systems. New hinges, levers, handles and plates had to be retrofitted and adapted to existing doors, closure mechanisms and panic assemblies. Cirecast worked with the architect and general contractor to identify historic hardware onsite which could be used as an example for new hardware that had to be designed and manufactured. In the case of an ornate backplate for a door pull, the only remaining sample was too small and had holes that had been drilled for the original bit key locks. Cirecast patternmakers were able to create new master patterns which were used to manufacture door pulls that rivaled the originals in quality.

Cirecast solved a typical problem that occurs during the restoration of historic buildings: the reuse of historic hardware while also providing ADA compliance, historic sensibilities, and maintaining campus wide interchangeable key compatibility. Cirecast created a new oval shaped master pattern for a Russwin unit lock that incorporated the same decorative detailing as the original knob. An interchangeable core gateway was machined to allow use of industry standard cores. New internal door parts were designed and produced so that the new knob would work properly. The results speak for themselves.
