The LCN 4011HALRH is a Grade 1 surface mounted door closer that installs on the pull side of the door. This heavy-duty hold-open closer uses Size 1 spring force to control doors up to 32 inches wide while providing the hold-open function that keeps doors open until manually released. The cast iron body with forged steel main arm handles high-traffic applications where consistent closing performance matters.
Built for commercial and institutional use, this closer features double heat treated steel pinion construction and all-weather fluid that performs in temperature extremes. The right-hand configuration mounts with TBSRT thru bolts for secure attachment to hollow metal or wood doors. The 689 aluminum finish provides corrosion resistance while matching standard hardware finishes.
