Well, if you don’t work for a locksmith company like I do, you probably haven’t ever wondered about the inside of a door closer. As long as door closers properly control the doors you go through, you probably don’t think about them at all.
But I am not the only one who finds facts about door closers fascinating! LCN Closers were recently profiled on The Fox Business Network in their “Manufacturing Marvels” series.* The two-minute profile featured LCN products and the company’s commitment to quality since their origin in 1880. The segment also raised awareness of how door closers help improve security by reliably closing and latching doors, ensuring that fire doors are closed and latched to prevent the spread of smoke and flames, and how door closers control doors to prevent slamming, damage and injuries.
A blog probably isn’t the best forum for flaunting features like “a 20% stronger rack and pinion design” or even the 4040XP’s “patented green dial which allows for accurate and no-fail power adjustments.” But this LCN product is on one of the most frequently visited pages of our website, and our lock techs install them in hospitals, schools, commercial buildings and sports facilities throughout our Chicagoland service area on a daily basis. There must be a reason for their popularity, and since they are so plain looking on the outside, it has to be because of how they are put together on the inside!
