Code-Ready Door Hardware

Door Hardware That Meets Code and Holds Up to Daily Use

Codes set clear rules for door hardware. Fire doors must close and latch by themselves, and they need a check each year. Accessible doors need easy-grip hardware, like levers, set 34 to 48 inches above the floor. Closers must give people at least five seconds to pass. Our technicians test, adjust, and replace hardware so your doors are ready for inspection day.
