The LCN 4011HALLH is a surface-mounted door closer that installs on the pull side of the door. This size 1 unit handles lighter doors while providing reliable self-closing action for NFPA 80 compliance. The hold-open feature keeps doors propped open until manually released, reducing wear in high-traffic areas.
Built with forged steel main arm and double heat treated steel pinion, this Grade 1 closer delivers commercial durability. The cast iron body contains all-weather fluid that maintains consistent performance across temperature ranges. Left hand configuration matches door swing direction for proper installation.
