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 delivers reliable performance in high-traffic commercial applications where controlled door operation is critical. The parallel arm configuration keeps the closer body away from the door swing path while maintaining consistent closing force.
Built with forged steel main arm and double heat treated steel pinion, this closer handles demanding commercial use. The all-weather fluid ensures consistent operation across temperature extremes. Delay adjustable timing lets you fine-tune the closing sequence for your specific application needs.
