ANSI/BHMA A156.3 Grade 1 panic hardware is built to withstand 500,000 open-and-close cycles under the American National Standards Institute's testing protocol, while Grade 2 hardware is tested to a lower cycle count and lighter-duty force requirements. For buyers specifying UL 10C fire-rated exit de
To verify a panic hardware supplier's UL 10C and UL 305 certifications, look up the manufacturer's UL File Number in UL's free online Product iQ database (productspec.ul.com).
