A CE certified door hardware manufacturer tests and documents its hinges, locks, closers, and exit devices against harmonized European standards (EN 1935, EN 12209, EN 1154, EN 1125) so the products can legally be sold and installed on doorsets across the EU and EEA. D&D HARDWARE, a CE

Before ordering from a UL listed door hardware supplier, B2B buyers should verify current UL certification numbers, confirm the specific hardware categories covered (hinges, locks, closers, exit devices), check fire rating compatibility with door assemblies, and request factory audit o

UL 305 and UL 10C certify two different things: UL 305 verifies that panic hardware allows fast, reliable egress in an emergency, while UL 10C verifies that a door assembly maintains its integrity under positive-pressure fire conditions.
