The LCN 4040XPREGAL is a heavy-duty surface mount door closer that installs on the pull side top jamb. This Grade 1 closer handles high-traffic commercial applications where standard closers fail from constant use. The cast iron body with forged steel arms delivers reliable operation in demanding environments.
The Green Dial system eliminates guesswork when setting spring power from size 1 through 6. Solid forged steel main arm and forearm resist bending under heavy loads. The spring-loaded stop in the soffit shoe protects the closer mechanism during over-opening. This closer adjusts to accommodate doors up to 5 feet wide for interior applications and 4 feet for exterior installations.
Understanding ANSI A156.4 requirements helps ensure proper Grade 1 performance standards. For specific spring sizing based on your door dimensions, reference our door closer selection guide to match closer capacity with door width and weight.
