LCN is committed to providing the best door closers in the world. In addition to the mechanical advantages derived from proven designs, much of the durability of the closer and arm system is directly related to the materials used in their manufacture. Precision machined cast iron cylinders and forged steel pistons work together because of the compatibility of their basic elements. Heat treated pinions and pistons spread the load over a large gear tooth system to better handle the wear and stress of millions of operating cycles. Upper and lower full compliment pinion bearings provide the support and load capacity required by the design of the closer. All weather fluid eliminates the need for seasonal adjustments. Forged steel main arms are superior to stamped steel arms used on closers where price is the primary concern. Specially designed shoe and elbow joints provide maintenance free service. A state-of-the-art, powder coat process delivers a high quality, corrosion resistant finish on all metal parts in popular architectural finishes. LCN always uses the best materials available to provide the exceptional value and long service life that you, our customer, have every right to expect.

 From schools and healthcare facilities, to sports arenas, government buildings and other commercial setting, LCN closers are the toughest, smoothest and most reliable door closers in the business.  The LCN surface mounted closers includes heavy-duty closers for interior and exterior doors and standard duty.
