The LCN 4111 is a heavy duty parallel arm door closer that mounts on the push side of the door frame. This Grade 1 closer handles high-traffic commercial applications where standard closers wear out quickly. The parallel arm configuration keeps the closer body away from the door swing path, reducing vandalism risk.
Built with forged steel main arm and double heat treated steel pinion, this closer delivers reliable performance in demanding environments. The all weather fluid maintains consistent operation across temperature extremes. Right hand configuration works with doors that swing away from you when standing on the hinge side.
