This door closer mounts to the push side top jamb and controls opening and closing force for right-handed doors. The LCN 4021 handles high-traffic commercial applications where reliable door control prevents damage while meeting accessibility requirements. The adjustable spring force accommodates doors of varying weight and width.
Cast iron construction with forged steel main arm and double heat treated steel pinion delivers long-term durability. All weather fluid keeps the closer operating in temperature extremes. The aluminum finish resists corrosion in exterior applications. Peel and stick templates speed installation with precise hole placement.
