Corbin Russwin

Tracing its distinguished heritage to 1839 when Russwin was founded by Henry Russell and Cornelius Erwin, and 1849 when Corbin was established by Philip and Frank Corbin, these two fierce competitors merged in 1902 to form The American Hardware Corporation, eventually becoming Corbin Russwin under Emhart Industries (1964) and Black & Decker (1989) before being acquired by ASSA ABLOY in 2000. Headquartered in Berlin, Connecticut, Corbin Russwin has produced high-quality commercial door hardware for over 180 years, maintaining its position as a leader in ANSI/BHMA Grade 1 mortise locks, cylindrical locks, exit devices, door closers, and electronic access control solutions. The flagship ML2000 Series mortise locks exceed Grade 1 requirements with heavy-gauge steel construction, patented status indicators providing 180-degree visibility, and Motorized Electric Latch Retraction (MELR) options, while the CLX3300 Series Grade 1 cylindrical locks blend elegance with strength for high-traffic applications. The ED5000 Series exit devices, including the ED5200 rim device with SecureBolt deadbolt-style latchbolt and ED5400/5800 vertical rod configurations, exceed Grade 1 standards with testing certified to over 3.25 million cycles (6x requirements) and carry 3-hour UL fire ratings for A-label doors. Door closer lines include the DC3000 Series (Grade 1, standard duty), DC6000 Series (heavy-duty), and DC8000 Series (premium heavy-duty for ADA compliance), all featuring cast iron construction, Quik-Install mounting plates, and proprietary Pyramid bow technology for consistent spring force. Electronic solutions span the SN200 Series with Wiegand/OSDP protocols, IN220 Power-over-Ethernet systems, and integration with HID Global's multiCLASS SE technology. Specialized offerings include HSS (anti-harm) behavioral health trim, the Georges and Muséo decorative collections, and comprehensive key systems with patent-protected keyways. All products meet stringent certifications including ANSI/BHMA Grade 1, UL/cUL listings for panic and fire exit hardware, ADA/A117.1 accessibility compliance, and are backed by 5-year warranties, positioning Corbin Russwin as the preferred choice for commercial, institutional, government, healthcare, and educational facilities demanding superior aesthetics, security, and durability in architectural door hardware.
