LCN
LCN pioneered the commercial door control industry. Lewis Carey Norton invented the pneumatic door check in 1880 after being commissioned to solve the problem of slamming doors at Boston's Trinity Church, and LCN closers have been manufactured in Princeton, Illinois ever since. Now part of Allegion, LCN builds the heavy-duty surface, track, concealed, and automatic door operators that spec writers default to on hospitals, schools, office buildings, and high-traffic openings needing to meet ADA opening force and NFPA 80 self-closing requirements.
The 4040XP Series and what we stock
The 4040XP Series is the LCN flagship, a Grade 1 cast-iron heavy-duty closer that has been the reference standard for commercial openings for decades. We stock LCN SKUs, all Made in USA, all cast iron, all Grade 1, all carrying ANSI/BHMA A156.4 listings. The catalog skews heavily to door closers and door-closer accessories. Browse our surface-mounted door closers and concealed door closers for the LCN SKUs we carry.
Standards and fire ratings
LCN hardware ships with ANSI/BHMA A156.4 Grade 1 listings and UL-cUL fire-rated configurations. The door closer selection guide walks through Grade 1 vs Grade 2, ADA opening force, fire-rated requirements, and adjustment troubleshooting; the fire door gasketing guide covers the rest of the NFPA 80 fire-door assembly. The full LCN catalog and CSI specs are at lcnclosers.com.
