FORMERLY MCKINNEY DOOR SOLUTIONS & AMERICAN DOOR PRODUCTS - NOW UNITED AS AMERICAN DOORS.
LCN’s history began in 1877 when the founder was hired to solve the problem of slamming church doors at Boston’s Trinity Church, leading to the invention of the world’s first practical commercial door closer. Now an Allegion brand, LCN has dedicated its resources to producing the finest line of door control devices, with innovations including the patented Green Dial, forged steel arms, Liquid X hydraulic fluid, and heat-treated steel components. Their products can be found in high-traffic facilities such as schools, hospitals, government buildings, and correctional facilities, with 35 different series of closers offering 15 to 20 years of operating life.
