The LCN 4040XP parallel arm surface closer mounts on the push side with the arm extending parallel to the door frame. This configuration keeps the closer body and arm out of the door opening, making it ideal for high-traffic corridors where protruding hardware creates obstacles. The parallel arm design handles the constant abuse of commercial environments while meeting ANSI Grade 1 cycle requirements.
Built with cast iron construction and forged steel arms, this closer delivers reliable performance in rugged applications. The Green Dial system eliminates guesswork when adjusting spring power from size 1 through 6, accommodating doors up to 5 feet wide for interior installations and 4 feet for exterior doors. Spring-loaded stops in the soffit shoe protect the closer from over-extension damage during heavy use.

This closer meets ANSI/BHMA A156.4 Grade 1 standards for commercial door control applications, providing the durability required for high-cycle installations.
The adjustable spring sizing accommodates various door weights and widths - reference our door closer selection guide for proper spring size matching to door dimensions. For broader understanding of Grade 1 door closer performance standards, ANSI A156.4 defines the cycle testing and force requirements that separate commercial-grade from residential hardware.
